I30-I52: Other forms of heart disease
I49: Other cardiac arrhythmias
Other cardiac arrhythmias refer to a group of heart conditions characterized by an abnormal heart rhythm. This abnormal rhythm may occur because the heart's natural pacemaker develops an irregular rhythm, or because the normal conduction pathway is interrupted. In some instances, another part of the heart takes over as pacemaker. Symptoms can vary according to the type of arrhythmia and may include palpitations, feelings of a pause between heartbeats, or an irregular pulse. Some people may not even experience symptoms. These conditions can develop from several factors such as heart disease, high blood pressure, diabetes, and excessive use of alcohol or caffeine. Progression of the condition can lead to severe outcomes like stroke or heart failure if left untreated. The cardiovascular system, specifically, the rhythm and functioning of the heart, is affected by these conditions.
