8 patients suffering transposition of the great arteries (d-TGA) aged from 8-17 years (mean 12.6 years) after Senning procedure performed were analyzed. Right atrium and right ventricle enlargement was detected in all patients. Small jet tricuspid valve regurgitation was confirmed in 5 patients, significant tricuspid valve insufficiency in 3 patients. 4 patients had presented with tricuspid valve, aorta valve and mitral valve insufficiency. In one patient insignificant pulmonary artery stenosis had been diagnosed. Chronic cardiac failure (NYHA III/IV) has been diagnosed in 2 patients, other patients from the analyzed group are in good clinical condition. All patients but 2 were diagnosed with arrhythmia using 24-hour Holter ECG. In 2 patients sinus node dysfunction was noted. Also supraventricular extrasystole, ventricular extrasystole, supraventricular tachycardia, ventricular salve, paroxysmal atrial fibrillation were described. No drug therapy in 4 patients is needed, one is treated with ACE-inhibitors, one with diuretic drugs. 2 patients suffering cardiac failure had been treated with 4 drugs, also temporary with intravenous dopamine. One death had been noted, caused by serious arrhythmia. One patient had been qualified for heart transplantation, there is no further data regarding this case. Senning procedure can be considered high risk for various problems, so patients who underwent this type of correction should be carefully observed.

Persistent fetal supraventricular tachycardia (SVT) with more than 210 bpm frequently leads to congestive heart failure. We report on a case with SVT and congestive heart failure that converted into sinus rhythm within 19 days of therapy with flecainide and beta-acetyldigoxin. A 32-year-old II gravida I para (25 + 1 weeks of gestation) presented with fetal SVT of 267 bpm. A non-immunologic hydrops fetalis was diagnosed by ultrasound showing ascites, pleural and pericardial effusion and tricuspid regurgitation. Within 19 days of combination therapy with flecainide and digoxin, cardioversion was achieved. After 36 days of therapy no more signs of cardiac failure could be detected. A healthy boy was born at 38 + 6 weeks of gestation. Although cardioversion is expected after 72 h of therapy according to the literature, this fetus converted into sinus rhythm on day 19 of therapy. This indicates that patients should not be considered resistant to treatment within the first 3 - 4 days.

Arrhythmia is the most common perioperative cardiac complication during noncardiac surgery. Most perioperative arrhythmia is benign, but fatal arrhythmia can occur, requiring emergency care. Arrhythmia is divided into tachycardia and bradycardia. Both arrhythmias often result in cardiac failure. Ischemic heart disease often causes premature ventricular contraction or ventricular tachycardia. Hypertensive heart disease or valvular heart disease can lead to atrial fibrillation or supraventricular tachycardia. Although patients may not have cardiac disease, hypoxia, hypovolemia, electrolyte disturbance, acidosis, and hypothermia can also cause arrhythmia. Patients with pacemakers or implantable cardiodefibrillators (ICDs) are affected by electric cauterization, which interferes with the sensing and inhibits the pacing of pacemakers as well as ICDs If this occurs, the mode of pacemakers and ICDs must be reset during surgery.

We report a case of a 26-year-old woman who presented to our hospital with arrhythmia and heart failure. She had an incessant supraventricular tachycardia, which was not reversible with electrical cardioversion. Echocardiogram showed a severe LV systolic and diastolic dysfunction. After radiofrequency catheter ablation, LV function returned to normal. This article is intended to show a case with tachycardiomyopathy, which is considered the most frequently unrecognized curable cause of heart failure, and to demonstrate that early treatment allows the recovery to a normal LV systolic and diastolic function, preventing irreversible structural cardiac damage. It is very likely that some patients with idiopathic dilated cardiomyopathy and chronic atrial fibrillation or other chronic arrhythmia actually have a curable tachycardiomyopathy.

20-30% of ICD patients suffer from inappropriate ICD therapy due to misclassification of supraventricular tachycardia (SVT) as ventricular tachycardia. Inappropriate ICD therapies are not only painful for patients, but also proarrhythmogenic and can reduce device longevity due to battery depletion. Therapy of inappropriate ICD episodes is a puzzle of optimized ICD programming, antiarrhythmic therapy and radiofrequency (RF) ablation. Single-chamber ICD detection algorithms are effective in reducing inappropriate ICD therapy particularly due to sinus tachycardia or atrial fibrillation. Dual-chamber ICD detection algorithms were developed to improve specificity of SVT discrimination. However, large prospective, controlled trials showing superiority of dualchamber over single-chamber devices are lacking. It appears that patients with slow ventricular tachycardias, being at high risk for inappropriate ICD therapy, might benefit from dual-chamber ICD therapy. Concerning pharmacological therapy of inappropriate ICD episodes, the OPTIC study recently showed superiority of class III antiarrhythmics (sotalol and amiodarone) over beta-blockers. RF ablation of cavotricuspid isthmus is of proven benefit in ICD patients with inappropriate episodes due to typical flutter and should also be considered in atrial tachycardia. If patients with paroxysmal atrial fibrillation despite optimized antiarrhythmic medication will benefit from trigger elimination or substrate modification by RF ablation has still to be proven. In patients with inappropriate ICD episodes and drug-refractory chronic permanent atrial fibrillation, AV node ablation can effectively eliminate inappropriate ICD therapy, however, at the price of potential ventricular asynchrony and progression of heart failure due to right ventricular pacing. Thus, upgrading to biventricular ICD therapy should be considered in these patients.

A 27-year-old pregnant woman was admitted with supraventricular tachycardia (SVT) and symptoms of heart failure. Echocardiography revealed pulmonary hypertension due to a tumour infiltrating the left atrium and compressing the pulmonary veins. After delivery by Caesarean section, the paroxysmal SVT was controlled by amiodarone. Thoracic CT scan showed mediastinal masses compressing the pulmonary arteries and veins, and a preliminary diagnosis of Hodgkin's disease was later confirmed by mediastinoscopy and lymph node biopsy. Following two courses of chemotherapy the masses diminished. The lumen of the left atrium increased, pulmonary hypertension and SVTs receded.

Sustained supraventricular tachycardia (SVT) may lead to life-threatening complications such as tachycardia-induced myocardial failure. We report the use of intravenous lidocaine in 5 dogs with SVT. Two dogs had evidence of an accessory conduction pathway, 2 were suspected of having an accessory pathway, and the mechanism of SVT was unknown in the remaining dog, which subsequently developed dilated cardiomyopathy 2 years later. In all cases there was rapid conversion to normal sinus rhythm, which was then maintained with oral mexilitene (4 dogs) or mexilitene combined with propranolol (1 dog).

Cardiac resynchronization therapy is an effective tool for the treatment of drug-refractory heart failure in patients with left ventricular dysfunction and inter/intra ventricular conduction delay. Supraventricular tachycardias may prevent effect delivery of this therapy. We report three cases in which effective therapy was limited by asymptomatic supraventricular tachycardia. Diagnostic pacing maneuvers were performed via the implanted device to determine the underlying arrhythmia mechanism. These cases highlight the importance of (1) treating supraventricular tachycardias before and after implantation of cardiac devices and (2) using device based programmed stimulation to diagnose the mechanism of supraventricular tachycardias.

A case of ventricular noncompaction with Giant P waves and focal atrial tachycardia is presented. A 36-year-old man was admitted to our hospital because of palpitations and a progressive worsening of heart failure. A 12 lead rest electrocardiogram showed large positive waves followed by smaller negative waves in limb leads and lead V1 which seemed to represent QRS complexes followed by retrograde P waves at first glance. Electrocardiogram revealed supraventricular tachycardia when palpitations occurred in this patient without any obvious triggers. Intravenous administration of amiodarone decreased the ventricular response by depression of conduction across the AV node which confirmed the diagnosis of focal atrial tachycardia.

Syncope occurring in patients with primary dilated cardiac disease has several causes: ventricular tachycardia (VT), a major severe cause of this diagnosis, occurring however only in one third of cases. The other causes are supraventricular tachycardia, bradycardia and vagal hyperactivity. The management depends on the etiology of syncope in one hand and the severity of the cardiac disease and other comorbidities in the other hand. In 2007, a patient with life expectancy exceeding one year, without irreducible heart failure but with a known and stable altered left ventricular ejection fraction (LVEF)<30%, will probably benefit of non-drug technology for the treatment of syncope (defibrillator with or without resynchronization), possibly in association with the treatment of another identified etiology, such as ablation or anti-arrhythmic treatment of a supraventricular tachycardia. In a patient with LVEF>30%, the electrophysiology exploration remains the most reliable recommended investigation for identifying the cause of syncope prior to discuss the implantation of a portable Holter device, indicated when the electrophysiology study is negative and syncope repeating.
