Tachycardia means ___ heart. The rhythm in which the atrial waves are seen as a sawtooth pattern is called: A) Premature Atrial Complex. B) Atrial Fibrillation. C) Atrial Flutter. D) Atrial Tachycardia. Fill in the blank. Paroxysmal atrial fibrillation ma...
A high heart rate increases myocardial oxygen consumption (because of increased workload) while impairing oxygen delivery. The impairment of oxygen delivery is due to the shortening of diastole at a higher heart rate; the coronary arteries perfuse the heart during diastole, which means that the ...
The name is from Latin. Supraventricular means "above the ventricles," which are the lower two sections of your heart. Tachycardia, pronounced(tack-eh-CARD-ee-uh), is what doctors call a fast heartbeat. Bouts of SVT can last from a few seconds to a few hours, and your heart can beat...
Following the observation that stretch and tachycardia show these distinctive patterns of gene regulation, we next concentrated on the common gene fraction with unidirectional regulation and identified a non-coding miR-1183 precursor gene—MIR1183, which stands out as the top up-regulated array transcri...
1. Do you see concordance present in the precordial leads (V1-V6)? Sometimes explained as the absence of a “RS complex,” concordance simply means “all up” or “all down.” A simple way to think of this would be to ask the question: Are all QRS complexes completely...
A tachycardia control pacer in which at least one scanned pulse is generated following each tachycardia confirmation, and the last- used pulse timing is retained following the next tachycardia termination for subsequent first use following the next tachycardia confirmation. The tachycardia termination detec...
the means for selecting selects one of the following pacing configurations: (i) pacing the right ventricle (RV); (ii) pacing the left ventricle (LV); and (iii) pacing the left ventricle (LV) and the right ventricle (RV), and the means (70, 72) for performing anti-tachycardia pacing ...
Typically, antitachycardia pacemakers attempt to terminate tachycardias when the heart rate exceeds a predefined high rate. Although this means for detecting a tachycardia has the advantage of simplicity, it has the disadvantage that it will detect and attempt to treat high rate sinus rhythms which ...
informed and instructed each participant about the intervention with individually tailored exercise, prescribed the dose of recommended exercise, and then managed weekly contact with each participant over the following 12-week intervention period. Since the intervention was individually tailored, the setti...
Of the recognized disorders of the cardiac mechanism, none possess greater interest than the paroxysmal tachycardias. This affection has been recognized as a clinical entity for more than thirty years, and the condition has been produced experimentally by various means. Two questions have recently bee...
