Cardiac arrhytmias is a term applied to disturbances of :
- frequency of heart beats
- regularity of heart beats
- origin of heart beats impulse
- Frequency
Increased frequency is described as /tachycardia
Decreased frequency is described as /bradycardia
- Regularity
Irregularity may be absolute - for example [atrial fibrillation]? or
with a pattern - for example bigeminia? or trigeminia?.
- Origin
In normal conditions heart beat impulses are generated in [sinoatrial node]?.
If the impulse is generated in other parts of the heart it is regarded as a
pathological phenomenon.
- Diagnosis
The most simple and effective diagnostic test for assesment of heart rhythm is
electrocardiogram? ( abbreviated ECG or EKG.
