There is a possibility of sudden death with a heart rate of 130 beats/min, but this is very unlikely because abnormal heart pumping function or abnormal heart beats have to occur first before sudden death can occur. Although the heart rate is 130 beats per minute, sudden death does not usually occur as long as the pumping function and pulsation are normal. If the heart rate is at 130 beats/min after strenuous exercise, it is a transient heart rate acceleration, which usually does not have any significant effect on the body and can be relieved after rest. However, in rare cases, the heart rate may continue to rise continuously for weeks to months, often appearing above 120-130 beats per minute, which can lead to tachycardia-mediated cardiomyopathy and the patient needs prompt treatment. If the heart rate is at 130 beats per minute after exercise, rest should be taken as soon as possible to restore a normal heart rate. If a heartbeat at 130 beats per minute persists without remission, prompt consultation with a cardiologist is recommended to treat the underlying cause and to ensure that there is no organic problem causing the rapid heart rhythm.
