cardiac arrhythmia

A disturbance in the electrical impulses to the heart which results in an irregular rhythm or rate of heartbeat.

cardiopathy, heart disease - a disease of the heart
flutter - abnormally rapid beating of the auricles of the heart (especially in a regular rhythm); can result in heart block
cantering rhythm, gallop rhythm - cardiac rhythm characterized by the presence of an extra sound; can indicate a heart abnormality
atrial fibrillation - fibrillation of the muscles of the atria of the heart
bradycardia - abnormally slow heartbeat
Adams-Stokes syndrome, atrioventricular block, heart block, Stokes-Adams syndrome - recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat
premature ventricular contraction, PVC - irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation
tachycardia - abnormally rapid heartbeat (over 100 beats per minute)
ventricular fibrillation - fibrillation of heart muscles resulting in interference with rhythmic contractions of the ventricles and possibly leading to cardiac arrest

1) Ventriculophasic sinus arrhythmia may occur with various forms of AV block, but is most typically seen with 2:1 AV block.
In addition, pulmonary stretch receptors are involved in the neural mediation of respiratory sinus arrhythmia (Taha 1995)-see further.
Sinus arrhythmia is variation of heart rate with phases of respiration i.
The different types of arrhythmia include Sinus arrhythmia, Tachycardia (fast heartbeat), Bradycardia (slow heartbeat), and Fibrillation (irregular).
A study reported a 34-year-old acclimatized patient with sleep apnea syndrome climbing mountain 7000 m above sea level and during sleep developed cyclic sinus arrhythmia with R-R intervals of up to 3.
The main periodic fluctuations found are respiratory sinus arrhythmia and baroreflex related and thermoregulation related heart rate variability (Akselrod et al.
The consensus of opinion is that HF respiratory component of R-R interval variability primarily reflects respiration-driven vagal modulation of sinus arrhythmia (21).
