For adults, a normal resting heart rate usually ranges from beats per minute (bpm).

: This signature sound is created by the snapping shut of the heart valves. The first sound ("lub") comes from the valves closing as blood pushes into the ventricles, and the second ("dub") occurs when the aortic and pulmonary valves close to prevent backflow.

Many patients with ectopic beats are asymptomatic. When symptoms do occur, they are often described as:

The ventricles relax, allowing blood to fill the left and right atria. For adults, a normal resting heart rate usually

Often, first-degree heart block has no symptoms at all. A doctor might discover it accidentally while checking an for a different reason. On an ECG, this condition presents as a prolonged PR interval, which is the time between the P wave (atrial contraction) and the QRS complex (ventricular contraction).
