There is a wide range of things that can lead to or cause an arrhythmia. A current heart attack or scar tissue from a previous attack can cause an irregular heartbeat. Specific health issues such as sleep apnea, diabetes, stress, high blood pressure, and thyroid problems can lead to an arrhythmia. Heart diseases like cardiomyopathy and coronary artery disease can cause heart rhythm problems. Smoking, drinking and drug abuse can also result in rhythm complications.
An arrhythmia can feel like the heart is racing or fluttering. Some arrhythmias will cause discomfort while others may only be noticeable through an examination.
Arrhythmia symptoms include:
- Decreased heartbeat
- Shortness of breath
- Chest pain
- Fluttering feeling in your chest
