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...

Triggering of nocturnal arrhythmias by sleep-disordered breathing events.

Nov 2009 OBJECTIVES: This study sought to evaluate respiratory disturbances as potential triggers for arrhythmia in patients with sleep-disordered breathing (SDB). BACKGROUND: SDB is associated with an increased risk of atrial fibrillation and nonsustained ... Read more...

Long-term prognostic value of ST-segment resolution in patients treated with fibrinolysis or primary percutaneous coronary intervention results from the DANAMI-2 (DANish trial in acute myocardial infarction-2).

Nov 2009 OBJECTIVES: The purpose of this study was to determine the prognostic value of ST-segment resolution after primary percutaneous coronary intervention (pPCI) versus fibrinolysis. BACKGROUND: Resolution of the ST-segment has been used as a surrogate ... 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;
