👉 In medicine, a "dyssystole" refers to an irregular or abnormal heart rhythm that occurs when the rate of contraction is not consistent with normal sinus rhythm. This can be caused by various factors such as stress, illness, medication, or other conditions. It's important to note that dyssystoles are often accompanied by symptoms like shortness of breath, chest pain, nausea, and dizziness. They may also lead to irregular heartbeat, increased risk of heart attack, and even death
