Anything is possible: But it's not likely. Bradycardia is defined as a heart rate <60. Heart rates of >50 are well tolerated by everyone. Heart rates of 40-50 during wakefulness sometimes cause fatigue. Sustained heart rates of <40 usually cause unacceptable fatigue and breathlessness. Pauses of > 3-5 seconds may cause dizziness. Pauses of > 5 seconds often cause blackouts. Pauses of > 2 minutes may cause death.
