Right ventricular apexangiography for precise placement of transvenous electrode catheters
Abstract:
A simple angiographic technique (right ventricular apexangiography) for positioning permanent transvenous pacemakers is described. With this technique, electrode failure occurred in only five (3%) of 186 patients followed for more than two years, as compared to an average failure rate of 23% in 11 reported series. Right ventricular apexangiography should be particularly useful in those patients in whom problems arise during insertion of a permanent transvenous electrode catheter.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
