Looking at the image of the heart beat diagram, we can say that the rhythm identified by selecting the single best answer is Sinus Bradycardia.
Sinus bradycardia is a heart rhythm where your heart beats slower than expected (under 60 beats per minute for adults) but otherwise works normally. It's fairly common, especially in adults over 65 and those who exercise regularly. It's usually not serious unless you have symptoms.
Sinus bradycardia is a type of slow heartbeat. A special group of cells begin the signal to start your heartbeat. These cells are in the sinoatrial (SA) node. Normally, the SA node fires the signal at about 60 to 100 times per minute at rest. In sinus bradycardia, the node fires less than 60 times per minute.
