Cardiac arrhythmias strike like lightning, with no warning. Even the slightest heart abnormality can cause arrhythmias, and it is well known that many patients with MVP experience them. In one article it states that a missed beat from being pulled over by a police officer is quite harmless and normal. This is not what most of us experience, and I believe everything should be done to lower our risks of sudden death due to arrhythmias. Proper testing should be done and treatment given accordingly.
Arrhythmias are disruptions in the natural rhythm of the heartbeat.
Bradycardia is an abnormal slow heart beat and Tachycardia is an abnormal increase in the resting heart rate. There are 2 types, supraventricular and ventricular. In both upper and lower chambers of the heart premature contraction that are early or extra beats can occur. These contractions are harmless in normal hearts, but in those with heart disease investigation needs to be done. This ineffective functioning results in an insufficient supply of blood being carried to the body tissues.
