Caption: Figure 1: On presentation, a 12-lead electrocardiogram showed ventricular tachycardia of a left bundle branch
morphology and superior axis.
Verapamil did reduce the amount of ST elevation and the frequency of bundle branch
block following chest impact.
6,7) It is also common to find tachycardia, ST and T wave changes, bundle branch
block, extrasystoles and prolongation of QT interval.
These observed irregularities in the cardiac rhythm took various forms 8 ECGs displayed PVCs, 3 had PACs, 2 had atrial fibrillation, 1 had missed beats and 1 had a bundle branch
At faster heart rates, this phenomenon occurs because of impulse falling in the relative refractory period of the bundle branch
cells, also referred to as "phase-3 block.
ACS--acute coronary syndrome MI--Myocardial infarction LBBB--left bundle branch
block UA--unstable angina GFR--glomerular filtration rate PRA--pre-renal azotemia CRS--cardiorenal syndrome
In those with left bundle branch
block, it was $22,086 per QALY.
His electrocardiogram showed sinus tachycardia with old complete right bundle branch
We gave the greatest strength of recommendation for patients with a wide QRS interval and left bundle branch
block, a modest recommendation for patients with a less wide interval, and an equivocal recommendation for those without left bundle branch
The syndrome of right bundle branch
block, ST segment elevation in V1 to V3 and sudden death is a clinical-electrocardiographic diagnosis based on syncopal or sudden death episodes in patients with a structurally normal heart with a characteristic electrocardiographic pattern.
As the preoperative electrocardiogram showed complete left bundle branch
block (LBBB) and the vertigo history, the patient was assigned to receive implantation of temporary pacemaker.
It covers topics ranging from sinus rhythm, ectopic and escape beats, and bundle branch
and fascicular blocks, to supraventricular tachycardias, atrioventricular junctional re-entrant tachycardias, and Wolff-Parkinson-White syndrome, to sudden cardiac death and cardiac pacing.
Electrocardiography showed a sinus rhythm with a complete right bundle branch
any kind of atrioventricular or intraventricular conditions or blocks such as complete left or right bundle branch
block, AV node block, QTc or PR prolongation, premature atrial contractions or other atrial arrhythmia, sustained ventricular arrhythmia, two premature ventricular contractions in a row, ST elevation consistent with ischemia)
Her electrocardiogram revealed right bundle branch
block escape rhythm (Fig.
