A study about gout associated with hypertension, diabetes, ischemic cardiopathy and different alterations in the sanguineous levels of lipids was conducted on 80 patients of the Rheumatology Service at the National Institute of Cardiology in Mexico City. We found abnormal levels of tryglicerids in the blood of 55% of the patients and a high level of cholesterol in only 5%. In 27% of the patients, some alteration showed in the carbo-hydrates methabolism, and in 22,5% of them we found systemic arterial hipertension. Slight ischemic cardiopathy was showing in a 37% of the patients, but uric acid level in blood seemed to be of little importance for the frequency, type or severity of the coronary heart disease. We made a comparison between the results we obtained through these studies and those found among the Mexican population and with information found in international medical publications.

In 127 cases (70 with cardiopathy, 41 with arteriopathy and 16 normals) a "chronomethryc clinical exploration" was performed. This procedure consists in obtaining an electrocardiogram at the same time a clinical examination is performed and in the very moment of the occurrence of a physical or oscilometric phenomenon the standardization marker of the electrocardiogram is actioned to register a mark indicating a Q-phenomenon interval. 3 of this intervals are measured for each clinical phenomenon and the two closest values are averaged. This method is based in the fact that the time of human reaction varies relatively little when 2 successive similar phenomena are appreciated (for ej.: 0.158 sec. +/- 0.036 (SD) and 0.154 sec. +/- 0.042 (SD), n = 32, P = non significant for the first and 2nd. auscultated cardiac sounds). In this way the following intervals were estimated: acustyc systole (n = 52), 2nd. sound-opening mitral snap interval (n = 17), duration of systolic cardiac murmur (n = 22), mechanic systole (n = 14), left ventricular eyection time (n = 15), and IIa-O interval (n = 17) and compared with their respectives phonographyc or apicography values with correlations coefficients of 0.58, 0.83, 0.73, 0.58, 0.70, and 0.70, respectively. The sistolic murmurs were classified in proto, meso or telesystolic and a good correlation was found with the phonography (method in 91.0% of cases). This procedure also identified correctly a left IV sound (n = 8) even in cases in which this sign formed a complex with the first heart sound.

The AA. studied segmental wall motion of the LV by means of 7 different methods. The study was performed in order to determine which reference system is the best for utilizing in subjects not affected by any heart disease. Two interesting points have emerged: first the methods which utilise the gravity center are the most sensitive; second, LV wall motion depends on the ejection fraction. In this perspective the AA. present a model of left ventricular motion.

In 78 consecutive patients with uniform ventricular ectopic complexes and without heart disease, ventricular couplets were present significantly more often when the coupling interval of ventricular ectopic complexes was variable than when it was fixed (P less than 0.04). In 69 consecutive patients with couplets, the prevalence of a variable coupling interval was significantly greater than that of (55 versus 14 cases; P less than 0.001). Among 55 patients with a variable coupling interval, ventricular parasystole was probable in 38 and possible in 17 patients. These results suggest that the association between ventricular couplets and parasystole is not coincidental. Of several possible mechanisms responsible for this association reentry within the parasystolic focus or its vicinity is the most probable. This may explain the observation that the couplets are seldom followed by consecutive ventricular ectopic complexes or ventricular tachycardia. If this hypothesis is correct, the clinical significance of ventricular couplets in the presence of ventricular parasystole may be similar to that of single reentrant ventricular ectopic complexes.

A case of pulmonary arteriovenous fistula associated with rheumatic mitral heart disease is presented. We have reviewed the literature and no published case with such association has been described. The loud mitral insufficiency murmur hide the continuous murmur of the fistula. The angiographic study demonstrated the A-V fistula. Retrospectively the diagnosis should have been suspected due to cyanosis, slight clubbing, the radiologic findings and the important Qs/Qt shunt. The associated pulmonary embolic phenomena made more difficult the diagnosis.

Paradoxical systemic embolism in the absence of congenital heart disease is often considered a clinical or pathologic rarity. We have recently observed two cases of paradoxical systemic emboli, secondary to massive pulmonary embolization in the presence of a patient foramen ovale in an otherwise normal heart. One case was lethal and the diagnosis was confirmed at autopsy. The other case was diagnosed by cardiac catheterization with dye dilution curves and the patient recovered after recurrences were prevented by the placement of an inferior vena cava umbrella-filter. Paradoxical embolization should be suspected when systemic emboli occur without an apparent cause. The diagnosis can be established by cardiac catheterization, pulmonary angiography and phlebography, and recurrences can be prevented by anticoagulation and partial interruption of the inferior vena cava, when the emboli arise from its territory.

In 94 patients with prominent left axis deviation, there was a marked disparity in the mean angles determined by the maximum magnitude of the deflections and that determined by areas. There was also considerable variation in the angle of the maximum vector in the frontal plane (frontal plane angle) and the angle of 50 msec vector in the frontal plane. Similar results were observed in 17 cases of ostium primum atrial septal defect. These differences contrasted with the findings in a normal group of 50 subjects where a close correlation was found. The initial vector was directed to the right in approximately 80% of normals and 60% of the patients with LAD indicative of conduction defects in the left anterior fascicular or its distal ramifications. We conclude that a rightward orientation of the 5--10 msec vector (i.e. causing a Q wave in lead 1) should not be required for diagnosis of left anterior fascicular block. The spatial orientation of the initial vector was always anterior in the control subjects. In these 'normals', as well as in the patients with left axis deviation, the initial vector varied markedly in its azimuth direction (right or left) when superiorly directed; but when inferiorly directed in the normal subjects it was virtually always directed rightward. From these data we were unable to construct rigid criteria which would reliably distinguish aberrant excitation patterns manifested by gross left axis deviation in the electrocardiograms of patients with established heart disease from subjects without defined heart disease. Old infarction patterns, anterior, inferior, and lateral were not obscured by the associated anterior fascicular block.

The direct body Bcg has been shown to reflect various expressions of the known physiological principles of cardiac dynamics. Emphasis has been placed on the identification and characteristics of the individual segment rather than on gross pattern variability for proper Bcg pattern evaluation. Its sensitivity in the detection of early myocardial infarction with particular attention to its initial HI forces has been described. The significance of the simple Master two-step test (double) in eliciting the amplification or deterioration of these forces as a measure of myocardial integrity has also been emphasized. With this proposed definitive direction, there is call for widely organized attempts to clarify its potential as an important adjuvant in the study of clinical heart disease.

Right and left ventricular systolic time intervals are measured in 40 cardiopathic subjects and compared with the respective values concerning 20 normal subjects. The results show a modification: a) of the values concerning the right ventricle in presence of pathology interesting this ventricle; b) of the values concerning the left ventricle in presence of pathology interesting this ventricle; c) of the values concerning both the ventricles in presence of left ventricular pathology which has, also, interested the right ventricle. The AA. emphasize the importance of the right and left ventricular systolic time intervals not only to separate pathology interesting the right ventricle from that interesting the left ventricle, but also, to evaluate the ventricular performance and the stage of evolution and extension of the cardiopathy.

20 subjects affected by ventricular pre-excitation, without any other associated cardiac disorder, underwent to maximal exercise test on bicycle ergometer; the aim of the research is to analyse their maximum levels of aerobic power, to study their electrocardiographic behaviour during exercise, with a particular reference to the ventricular repolarization, and finally to evaluate the incidence of arrhythmias during exercise. The maximum aerobic power was slightly lower than the reference standards (on average 78.32%); the muscular work, in 1 patient only, gave rise to cardiac arrhythmias during exercise. In these patients we assume as non specific, the "like ischemic" variations of the ventricular repolarisation during exercise.
