Sick sinus syndrome is a heartbeat disorder frequent among the elderly.

Patients will have cardiac arrest if they do not receive CPR or defibrillation. Ventricular fibrillation (V-fib) is the most life-threatening arrhythmic condition because the heart muscles quiver but do not contract or pump blood there is no blood circulation or pulse.However, in those with heart disease, it can lead to a medical emergency. Ventricular tachycardia may not pose any symptoms in some people with a healthy heart. The heart beats so fast that there is inadequate blood to fill the ventricles to pump to the body. Ventricular tachycardia is the abnormal heart rhythm due to erratic electrical signals in the ventricles (the heart’s lower chambers).Supraventricular tachycardia develops due to erratic heartbeat in the heart’s upper chambers.Atrial flutter occurs when the atria (upper heart’s chambers) beat too rapidly but more rhythmically than A-fib.A-fib is associated with other severe complications such as stroke. However, left untreated, some people may have a continuous A-fib rhythm. Atrial fibrillation (A-fib) results from chaotic cardiac signals, leading to temporary uncoordinated racing heart rhythm.Bradycardia (slow heartbeat) is when the resting heartbeat is less than 60 beats per minute.Tachycardia (fast heartbeat) is when the resting heartbeat is over 100 beats per minute.However, maintaining a healthy lifestyle can lower the risk of developing heart arrhythmias. To treat heart arrhythmia, your doctor may prescribe medications, perform catheter procedures, or device implantation. Some heart arrhythmias can be harmless, while others can be life-threatening. You may experience a heart that is racing or fluttering. When your heart beats irregularly due to faulty electrical signals, it may be due to a heart arrhythmia. People can have a fast heartbeat during exercise or a slow heartbeat while sleeping.
