Bradycardia is a condition characterized by a slower than normal heart rate. While a normal adult heart beats between 60 and 100 times per minute, bradycardia is defined when heart rate falls below 60 ...

Tachycardia-bradycardia syndrome (i.e. pauses after converting to sinus rhythm) Severe sinus bradycardia Sinus pauses/sinus arrest Sinoatrial nodal exit block Chronotropic incompetence (failure of ...

and prolonged sinus pauses after AF termination, which is also known as tachycardia-bradycardia syndrome. When antiarrhythmic drugs (AADs) are administered for rhythm or ventricular rate control ...

A “sinus pause” ensues afterward and would be shorter ... When a junctional escape ensues, the rhythm may be confused with a junctional rhythm. If no junctional escape rhythm is present ...

The longest documented pause is 15 seconds – a very long time to wait for your next heartbeat! “For the very first time, we have tested an alternative hypothesis that there is a circadian rhythm in ...

With a sustained block of the SNS, the researchers observed loss of the day-night rhythm in sinus node pacemaking and in pacemaking ion channels. Surprisingly, the heart’s local circadian clock ...

Furthermore, the proportion of time in sinus rhythm whilst on assigned antiarrhythmia therapy did not effect these outcomes in the 1,316 patients for whom electrocardiograms were available.

[18] For the purposes of the present study, rhythm disturbances contemplated included sinus tachycardia, sinus bradycardia (SB), pauses of > 2 s, premature supraventricular beat (PSVB), SVT ...
