What if your heart were to beat 4000 beats per minute?

If your heart were to beat 4000 beats per minute, it would be far beyond the physiological limits of human life, likely leading to immediate cardiac arrest. The heart would struggle to effectively pump blood, resulting in inadequate oxygen and nutrient supply to vital organs. Such a condition is incompatible with life, as the body requires a stable and controlled heart rate to function properly. In essence, a heart rate this extreme would be fatal almost instantly.
