Prediction of cardiac events in patients having left bundle-branch block
with/without chest pain using dipyridamole technetium-99m-sestamibi myocardial perfusion imaging.

Left bundle-branch block
is associated with increased 1-year sudden and total mortality rate in 5517 outpatients with congestive heart failure: A report from the Italian network on congestive heart failure.
Lightning victims may present with sinus tachycardia, transient ST-segment elevation or depression, QT prolongation, premature ventricular contractions, atrial fibrillation, or bundle-branch block
A 12-lead electrocardiograph (Figure 1) showed atrial fibrillation with ventricular pacemaker spikes associated with right bundle-branch block
, rather than the typical pattern of left bundle-branch block
Patients with an electronically paced ventricular rhythm (C) or left bundle-branch block
(B) require myocardial perfusion imaging.
The study enrolled patients with ST segment-elevation MI or new bundle-branch block
, presenting within 12 hours of symptom onset.
These three key factors are patient age 75 years or greater, Killip class II-IV, and an ECG demonstrating anterior MI and/or left bundle-branch block
, said Dr.
