Animal studies have suggested that spontaneous or programmed ventricular beats that occur simultaneously with atrial activation may facilitate atrioventricular (AV) nodal conduction during subsequent atrial impulses. However, this possibility has not been systematically studied in the human heart. In the present study the AV nodal conduction during a programmed atrial premature beat (S2) was an...

The QRS morphology of the 12-lead ECG of 41 morphologically distinct ventricular tachycardias (VT) was correlated with their site of origin as determined by catheter and intraoperative mapping. Twenty-two VT patterns had a right bundle branch block (VT-RBBB) morphology and 19 a left bundle branch block (VT-LBBB) morphology. All VT-RBBBs arose in the left ventricle. All 16 VT-LBBBs in patients w...

We describe two patients with posterior myocardial infarction (PMI) with unusually atypical clinical presentations and cardiac enzymatic profiles, but with the abrupt development of complete AV block in patient 1, and Mobitz II second-degree AV block with paroxysmal phases of higher degrees of AV block in patient 2, and mitral regurgitation leading to symptomatic pulmonary congestion. Also, bot...

BACKGROUND Conduction disorders (CD) and atrial arrhythmias (AA) in the postoperative period of cardiac surgery impede prompt clinical recovery and prolong hospitalization. Mitral valve repair (MVR) has become the treatment of choice for patients with significant valvular regurgitation, but information on CD and AA in this population is scarce. METHODS Records of consecutive patients undergoi...

In this longitudinal study 5,710 people were included. The inclusion criteria were two positive serological results for Trypanosoma cruzi infection, 15 and 50 years old and no other demonstrable disease at the time of study. In the five year follow up 1,117 patients were lost. The follow up involved yearly evaluation of serology, clinical examination, X-ray of thorax, and ECG, for 4,593 patient...

The importance of ventricular premature beats (VPB) in the clinical diagnosis of myocardial infarctions has been pointed out by several authors. Dressler (1943) reported a case in which the electrocardiographic signs of infarction were present in such beats (deep and slurred Q waves in lead III) and absent in the sinus beats. Simonson et al. (1945), Bellet (1953), Scherf and Schott (1953), Katz...

To explore the abnormalities in Iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. Body-fat percentage and resting 12-lead ECGs were recorded from all participants. Of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. A total of 84% of the athletes demons...
