An arrhythmia may cause symptoms like palpitations, skipping of the heart, dizziness, lightheadedness or feeling like you might pass out. An arrhythmia may also be totally asymptomatic, and one may not be aware of the irregular heart rhythm.
There are various types of arrhythmias including some with fast heart rates and some with slow heart Rates.
One common type of arrhythmia is atrial fibrillation. Atrial fibrillation may require blood thinners for stroke prevention.
