WebJan 20, 2024 · An ECG detects your heart's electrical rhythm and produces what's known as a tracing, which looks like squiggly lines. This tracing consists of representations of several waves that recur with each heartbeat, about 60 to 100 times per minute. The wave pattern should have a consistent shape. WebIn an EKG, the P wave is generated when the atria depolarize As blood is pumped out of the heart and into the major arteries leaving the heart, it pushes against the semilunar valves …
