ECG-derived parameters predict SR maintenance during 1-year follow-up after ECV at least as good as known clinical predictors of rhythm outcome. The DF proved to be the most powerful ECG-derived predictor.doi:10.1016/j.hrthm.2016.01.004Theo Lankveld...
Define Sinus tachycardia. Sinus tachycardia synonyms, Sinus tachycardia pronunciation, Sinus tachycardia translation, English dictionary definition of Sinus tachycardia. n. A rapid heart rate, especially one above 100 beats per minute in an adult. tach′
until a P-QRS-T complex is dropped. Notice the underlying rhythm is sinus bradycardia before and after the sinus pause. The P-P interval during the sinus pause is not a multiple of the baseline P-P interval on the ECG, which helps differentiate this rhythm from a second-degree SA block...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. Th...
Palpitation,ECG indicated sinus rhythm,75 beats/min,and premature occurrence of a wide QRS complex (its duration was 0.14 second ),no P wave before the wide QRS complexes. The diagnosis was A. Sinus rhythm,Premature atrial contraction B. Sinus rhythm,Premature ventricular contraction C. ...
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...
The heart acts as a pump and maintains circulation of the blood by alternate concentration and relaxation of cardiac muscle (the myocardium). It generally contracts at a rate of 70 to 75 beats/minute in a healthy 70-kg person at rest. The normal heart rhythm, known as sinus rhythm, origin...

Sinus bradycardiais a regularsinus rhythmbut with aSA noderate below 60bpm (Fig. 41.6). The ECG has normalP wavesand P–R intervals and a 1:1 conduction ratio between theatriaand ventricles, but an atrial rate of less than 60bpm. It represents a suppression of the SA node discharge rate...
