Heartbeat- Fast

The heartbeat is the noise generated by the beating heart and the resultant flow of blood through it. In healthy adults, there are two normal heart sounds often described as a "lub" and a "dub", that occur in sequence with each heart beat. At 91 bpm, this persons heart rate is toward the higher end of the range of normal adults. A little bit faster, and this person might have Tachycardia, a condition in which a resting heart rate is more than 100 beats per minute.
