"Also, a pacemaker can regulate the heart's rhythm, speeding up the heart rate as needed." Additionally, Duggirala says if hypothyroidism or sleep apnea is causing bradycardia, treatment of the ...

Bradycardia refers to a resting heart rate that is slower than usual. A heart rate of fewer than 60 beats per minute (bpm) may indicate an underlying health issue, but this is not always the case ...

Sinus rhythm (a.k.a. normal sinus rhythm) refers to the normal heart beat originating from the sinoatrial node. This is manifested as an upright P wave in lead II of the ECG. Sinus bradycardia ...

In fact, up to 60% of athletes demonstrate ECG changes (in isolation or in combination) such as sinus bradycardia, sinus arrhythmia, first-degree atrioventricular (AV) block, early repolarisation, ...

Sinus bradycardia occurs on an ECG when there is ... Note that an ectopic atrial rhythm occurs when the P wave is not upright in lead II. This indicates that the action potential is arising ...

An irregular heartbeat is a condition that occurs when the heart's electrical impulses are either too fast, slow or ...

which is also known as tachycardia-bradycardia syndrome. When antiarrhythmic drugs (AADs) are administered for rhythm or ventricular rate control in this subset of AF patients, a permanent ...

The system treats patients with abnormal or slow heart rhythms, symptomatic bradycardia, high-grade AV block, complete heart block, and sick sinus syndrome. Gary Allore, president of Trinity ...

The patient had classic tachycardia–bradycardia syndrome with periods of rapid rate during AF and slow rates during sinus rhythm, sleep or drug treatment. OSA may impact the occurrence of AF by ...
