premature atrial contractions (PAC)
may be triggered or increased by stress, caffeine, smoking, and some medicines. Cold remedies containing ephedrine or pseudoephedrine have been known to increase the incidence of atrial ectopic beats
the first symptom of AEB is usually a feeling that the heart has skipped or missed a beat. This is often accompanied by a feeling that the heart is thumping or pounding in the chest
Atrial ectopic tachycardia
Ventricular ectopic beats are easily seen on an electrocardiogram
The absence of a P wave on an EKG could indicate an issue with the electrical impulse formation in the atria of the heart, such as in atrial fibrillation where the atria are not depolarizing in a coordinated manner. Other possible causes include atrial flutter, junctional rhythm, or ectopic atrial beats. Further evaluation by a healthcare professional is necessary to determine the underlying cause.
Basically the heart is having extra beats, but it is unclear if those beats are from the atria or ventricles.
What could the prognosis be with a women in her late 40s with underlyning sinus rhythm, mixed with VEBs and AEBs? average rate of 57bpm ( range 37-143bpm) Heart rate less than 50bpm were noted 57% but with no pauses greater than 2 seconds. with sinus bradycardia, rate 52bpm and ventricular premature beat? women doesnt smoke, drink or take drugs of any kind. thank you
Atrial Flutter is characterized by rapid depolarization of a single atrial focus at a rate of 250-350 BMP
Premature atrial contractions or PAC's are heart beats that starts in the atria but from a different source than the normal pacemaker and sooner that the "normal" beats.They can occasionally be felt, usually as a few rapids beats while at rest, and can be suppressed if bothersome, but are generally not harmful.
One sound is the atrial beat, the other the ventricular one.
Bigeminy is an abnormal heart rhythm where every other beat is abnormal. This can be an abnormal atrial beat (atrial bigeminy), a beat arising from the AV junction or bundle of His (junctional bigeminy), or a ventricular beat (ventricular bigeminy). The pattern is as such: Normal beat... abnormal beat... normal beat.... abnormal beat... normal beat... abnormal beat... repeat.
