A team of doctors published a suspicious case report in 2012 of a man whose heart rate increased to 600 beats per minute. It is a full 300 beats more than the theoretical 300 beats per minute.
The case report talks about how a 57-year-old quadriplegic male came to the hospital with complaints of chest pressure and dizziness. After his examination, the doctors gave him nitrates and heparin for acute recovery syndrome. Moreover, they also kept him on tests and observation.
On the third day of his admission, he suffered several chest pain episodes and tachyarrhythmia. Furthermore, during one of the episodes, his heart rate spiked to 600 bpm for approximately 20 seconds before decreasing to 300 bpm gradually. However, it spontaneously returned to normal after the episodes.
Similar Heart Rate Cases
Doctors have noted similar cases in the past where patients’ heart rates spiked with the previous highest being 480 bpm.
The doctors added,
However, these cases require an explanation because multiple cases including the observed case were above theoretical heart rate.
The team said,
Moreover, with abnormal physiology of the heart, a mechanism could be allowing the heart to beat a lot faster.
However, with abnormal cardiac physiology, there could be mechanisms that allow the heart to beat much faster.
The team suggested that the likely explanation was AF and the presence of multiple bypass tracts in the heart.
