3. Ectopic beat - Wikipedia

   en.wikipedia.org/wiki/Ectopic_beat

   An ectopic beat can be further classified as either a premature ventricular contraction (PVC), or a premature atrial contraction (PAC). [ 1 ] Some patients describe this experience as a "flip" or a "jolt" in the chest, or a "heart hiccup", while others report dropped or missed beats.

4. Premature heart beat - Wikipedia

   en.wikipedia.org/wiki/Premature_heart_beat

   A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...

5. Junctional rhythm - Wikipedia

   en.wikipedia.org/wiki/Junctional_rhythm

   Accelerated junctional rhythm is when the rhythm of emerged impulses is more than 40 to 60 beats per minute, which is the natural range of the junction. It happens in some instances such as digoxin toxicity, and usually has a rate of between 60 and 100 bpm. [11]

6. Arrhythmia - Wikipedia

   en.wikipedia.org/wiki/Arrhythmia

   The normal heart rate of the fetus is between 110 and 160 beats per minute. Any rhythm beyond these limits is abnormal and classed as a fetal arrhythmia. These are mainly the result of premature atrial contractions, usually give no symptoms, and have little consequence.

7. Bigeminy - Wikipedia

   en.wikipedia.org/wiki/Bigeminy

   For example, in ventricular bigeminy, a sinus beat is shortly followed by a premature ventricular contraction (PVC), a pause, another normal beat, and then another PVC. [1] In atrial bigeminy, the other "twin" is a premature atrial contraction (PAC).

   en.wikipedia.org/wiki/Palpitations

   The cardiac etiologies of palpitations are the most life-threatening and include ventricular sources (premature ventricular contractions (PVC), ventricular tachycardia and ventricular fibrillation), atrial sources (atrial fibrillation, atrial flutter) high output states (anemia, AV fistula, Paget's disease of bone or pregnancy), structural ...
