If you’re concerned you might have an arrhythmia, trust Dr. Alireza Nazeri, your Cardiologist and Cardiac Electrophysiologist in Houston, TX at Mobitz Heart & Rhythm Center for the quality care and treatment you need.
What Is Arrhythmia?
In simple terms, an arrhythmia is an abnormal or irregular heartbeat. It is also referred to as dysrhythmia.
While pulses and heartbeats vary to some degree from person to person, each heartbeat tends to follow the same basic rhythm. However, sometimes, it can feel like the heart has skipped a beat, is beating faster or slower than normal, or is fluttering.
Changes such as these usually indicate arrhythmias, especially if there is no cause for the change. For example, your heart will likely beat faster when you are excited or exercising. However, if you’re sitting still and nothing else is going on, changes typically mean a heart rhythm disorder. They are not always dangerous, but you should visit Dr. Nazeri, your Cardiologist and Cardiac Electrophysiologist in Houston, TX, to be safe if you experience symptoms of arrhythmia.
Types of Heart Rhythm Disorders
There are several types of arrhythmias, the most common of which include:
- Bradycardia- Heart rate lower than 60 beats per minute
- Bradyarrhythmias- Slow heart rate due to a disease in the cardiac conduction system, which controls the heartbeat
- Tachycardia- Heart rate above 100 beats per minute
- Ventricular arrhythmias- occur in the lower heart chambers
- Supraventricular arrhythmias- occur in the upper heart chambers
