ECG findings of acute myocardial infarction and atrioventricular block during a transseptal procedure for left atrial ablation.

Clinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Epigastric pain in a 63-year-old woman. Atrial flutter with 2:1 atrioventricular block; acute inferoposterior myocardial infarction.

Effet of low-dose Aspirin on mortality of Acute myocardial Infarction

SUMMARY Between Aug. 1982 and March 1984, In a prospective, randomized trial approximately 24 hours after the onset of acute myocardial, infarction (MI), the influence of Low dose aspirin (120-150 mg/day, just during inhospital phase), on inhospital and post- hospital mortality rate was studied in 62 patients, and compared with control group. The two groups were comparable with regard to age,...

Accelerated atrioventricular conduction after myocardial infarction. A study using His bundle electrograms.

His bundle recordings obtained in a patient with progressive shortening of the PR interval observed during and after acute diaphragmatic myocardial infarction showed abbreviated AH and HV intervals. Though atrial pacing at rapid rates produced prolongation of the AH interval, this was not as great as is seen in normal subjects and the abbreviated HV interval remained unchanged. The results of H...

Baseline left bundle branch block with right bundle branch escape complexes in a patient with coronary artery disease, presents like an alternating bundle branch block: a case report

Alternating bundle branch block (ABBB) is a less commonly encountered phenomenon with the advent of re-perfusion therapy for acute myocardial infarction. ECGs simulating the appearance of an ABBB need to be carefully analysed. We present an ECG showing a baseline Left Bundle Branch Block(LBBB) progressing to a high grade AV block with escape complexes having a Right Bundle Branch Block (RBBB) m...
