Is it normal for heart rate to be in the 40s while asleep?
A doctor has provided 1 answer
Not normal but:: No, it is not normal to have a heart rate in the 40's. Normal heart rate is 60-100 though usually 60-80. However, if this is only during sleep it may not be a sign of anything serious. But it is probably wise to be evaluated by a cardiologist just to be certain this is not a sign of a variety of potential causes- see https://my.clevelandclinic.org/health/diseases/17841-bradycardia for more info.
