He had a low level of thyroid stimulating hormone (TSH) of <0.03 micro-lU/mL (normal range: 025-4.00) and a high free thyroxine (T4) level of 2.43 ng/dL (normal range: 0.89-1.79 ng/dL). Therefore, hyperthyroidism was diagnosed, and 5 mg of methimazole was administered twice a day....
Tachycardia itself is a heart rate that exceeds the normal range, generally a heart rate of over 100 beats per minutes. A Tachycardia can be caused by a number of factors which are usually benign. But some types of tachycardia, like ventricular tachycardia, can be dangerous due the speed ...
A normal sinus wave pattern interruptingwide-complex tachycardia Capture beatshave a normalQRS complexduration; aP wavemay also be visible. Caused by the occasional supraventricular impulse that passes through theAVNto cause ventriculardepolarization ...
sinus tachycardia (ST) a rapid rhythm originating in the sinoatrial node with a rate of usually 100 to 160 beats per minute; conduction through the ventricles is normal. During exercise or stress this is normal, but if it occurs during rest it is abnormal. supraventricular tachycardia a combina...
Tung R, Vaseghi M, Frankel DS, Vergara P, Di Biase L, Nagashima K et al. Freedom from recurrent ventricular tachycardia after catheter ablation is associated with improved survival in patients with structural heart disease: an International VT Ablation Center Collaborative Group Study. Heart Rhythm...
Bradycardia means: A. normal heartbeat B. fast heartbeat C. slow heartbeat D. irregular heartbeat Can an EKG show ventricular contraction? Why or why not? Fill in the blanks. When the ECG tracing shows only ventricular tachycardia, it is called ___ or...
10 s of 12-lead ECG recording were obtained with the EP system and then the animal was paced out of the rhythm using the ICD antitachycardia pacing algorithms. If burst pacing failed, the animal was shocked internally from the ICD. If VF was induced, the animal was immediately shocked ...
LVEF: Left ventricular ejection fraction NSVT: Non-sustained ventricular tachycardia NYHA: New York Heart Association RV: Right ventricle/right ventricular RVEF: Right ventricular ejection fraction RVFWS: Right ventricular free wall strain SAx: Short axis SCD: Sudden cardiac death ...
Left ventricular func- tion appeared normal (Table I) and a significant reduction in complex ventricular arrhythmias was re- corded. An electrophysiologic study was performed and 1 episode of nonsustained monomorphic ven- tricular tachycardia was induced. Right ventricular endomyocardial biopsy revealed ...
Often however, 1 or at most 2 or 3 re-entrant circuit morphologies are observed from any location driving ventricular tachycardia in both canine models and clinical studies 15, 16; thus, it would not seem likely that this model would be valid in all cases. Download: Download high-res image...
