Arrhythmia is a condition where the heart beats with an irregular rhythm. This can be caused by a variety of factors, including heart disease, electrolyte imbalances, and stress. Arrhythmias can be dangerous, as they can lead to heart failure or even death. Treatment for arrhythmias typically involves medications to help regulate the heart rate. In some cases, electrical cardioversion may be necessary to restore the heart’s normal rhythm.
Types of cardiac arrhythmias include: –
Sinus arrhythmia: Sinus arrhythmia is a relatively common type of arrhythmia, and usually isn’t cause for concern. It occurs when the heart rate speeds up or slows down in response to changes in the body, such as during exercise or after eating. Palpitations in the chest, shortness of breath, anxiety, lightheadedness, and dizziness are just some of the symptoms that can come with arrhythmia.
Tachycardia: Tachycardia is the most common type of arrhythmia. It is defined as a heart rate that is greater than 100 beats per minute. Tachycardia can be caused by a variety of things, including stress, anxiety, dehydration, and fever.
Palpitations: Palpitations are a common symptom of arrhythmia, and are often the first sign that something is wrong. Palpitations feel like your heart is skipping a beat, fluttering, or beating too hard or fast.
Respiratory sinus arrhythmia: RSA is the normal variation of heart rate that occurs in synchronization with the respiratory cycle. RSA is usually greatest during inhalation and least during exhalation. During deep breathing, RSA may approach 30 beats per minute.
