Related to Normal sinus rhythm: Sinus tachycardiarhythm (rĭth′əm) n. 1. Movement or variation characterized by the regular recurrence or alternation of different quantities or conditions: the rhythm of the tides. 2. The patterned, recurring alternations of contrasting elements of sound or spe...
Heart rate variabilityNormal sinus rhythmSinus tachycardiaHeart Rate Variability (HRV) is a biological process that indicates any disturbances in the time duration between heartbeats. It is quantified by the number of disturbances in beat to beat interval and the contrast observed in heart rate may ...

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...

Sinus Arrhythmia Sinus arrhythmia is present when the P wave morphology is normal and consistent and the P-P intervals vary by more than 120 milliseconds (or by more than 10% of the shortest...
palpitate, flutter - beat rapidly; "His heart palpitated" thrash - beat so fast that (the heart's) output starts dropping until (it) does not manage to pump out blood at all beat - indicate by beating, as with the fingers or drumsticks; "Beat the rhythm" ...
When sick sinus bradycardia begins to be of significant impact to the patient’s life, a pacemaker is usually implanted to keep the heart beating in normal sinus rhythm. Pacemaker implantation has a high rate of success in treating sick sinus bradycardia, however, in very young children, the ...

This term refers to the cyclic rise and fall of the heart rate in rhythm with breathing. Laymen tend to consider a steady, unvarying heartbeat a good sign, perhaps because skipped beats, palpitations, extra beats, and a racing heart all seem to involve deviations from clock-like steadiness....
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...
