The relationship of bipolar left ventricular pacing stimulus intensity to cardiac depolarization and repolarization in humans with cardiac resynchronization devices.

13 Dec 2009 BACKGROUND: Myocardial depolarization can be altered by varying pacing stimulus output. This may have implications on response rates for cardiac resynchronization therapy (CRT). The purpose of our study was to determine the relationship of left ... Read more...

Short-term hemodynamic effects of cardiac resynchronization therapy in patients with heart failure, a narrow QRS duration, and no dyssynchrony.

10 Oct 2009 BACKGROUND: Cardiac resynchronization therapy produces both short-term hemodynamic and long-term symptomatic/mortality benefits in symptomatic heart failure patients with a QRS duration >120 ms. This is conventionally believed to be due principally ... Read more...

Electrocardiographic predictors of atrial fibrillation.

29 Sep 2009 BACKGROUND: Atrial fibrillation (AF) is the most prevalent arrhythmia in the United States and accounts for more than 750,000 strokes per year. Noninvasive predictors of AF may help identify patients at risk of developing AF. Our objective was to ... Read more...

Technical information about 'Electrocardiography'

Definition: Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.

Descriptor UI: D004562

Alternative terms: Electrocardiography; EKG; ECG; Electrocardiogram; Cardioscope; Cardioscopes;

Allowable Qualifiers: adverse effects; classification; drug effects; economics; history; instrumentation; methods; mortality; nursing; psychology; radiation effects; standards; trends; utilization; veterinary; statistics & numerical data; contraindications; ethics;
