The body's fluctuating response to dramatic changes in vital signs, akin to a Valsalva maneuver, can disturb the heart's electrical rhythm. This disruption can lead to arrhythmias, which may be life-threatening, particularly for individuals with existing heart problems. Elvis Presley, who had a compromised heart, fell victim to this risk.

Arrhythmia is noted as the cause of death in Presley's autopsy report, highlighting how the body's reaction to physiological stress can have dire consequences. This illustrates the delicate balance within the body's systems and the severe outcomes that can arise when that balance is disrupted.
