Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. [1] This is different from normal pacemaking activity, where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm. Causes of wandering atrial ...
Agonal heart rhythm is usually ventricular in origin. Occasional P waves and QRS complexes can be seen on the electrocardiogram. The complexes tend to be wide and bizarre in morphological appearance. [1] Clinically, an agonal rhythm is regarded as asystole and should be treated equivalently, with cardiopulmonary resuscitation and administration ...
New devices are able to store a total of 60 minutes of recordings on their memory. Thirty minutes is reserved for automatic storage of arrhythmias according to preprogrammed criteria. The remaining 30 minutes can be divided into a selectable number of slots for storage of manually triggered retrograde recordings as an answer to symptoms ...

[6] The escape rhythm typically originates in the ventricles, producing a wide complex escape rhythm. Third-degree heart block may also be congenital and has been linked to the presence of lupus in the mother. [7] It is thought that maternal antibodies may cross the placenta and attack the heart tissue during gestation. The cause of congenital ...
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
Andersen–Tawil syndrome, also called Andersen syndrome and long QT syndrome 7, is a rare genetic disorder affecting several parts of the body. The three predominant features of Andersen–Tawil syndrome include disturbances of the electrical function of the heart characterised by an abnormality seen on an electrocardiogram (a long QT interval) and a tendency to abnormal heart rhythms ...
In a normal heart beat rhythm, the SA node usually suppresses the ectopic pacemaker activity due to the higher impulse rate of the SA node. However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm.
