"WebAn electrocardiogram is also known as an ECG; the Dutch and German version of the word, elektrokardiogram, is shortened to EKG. It is a tool used to visualize, or “gram,” the electricity, or “electro,” that flows through the heart, or “cardio.” Specifically, a 12-lead ECG tracing shows how the depolarization wave, which is a wave of positive charge, moves … " - First positive deflection in ekg

Webbetween 2 leads. A wave that is travelling towards the positive (+) lead will inscribe an upwards deflection of the EKG; conversely a wave traveling away from the positive lead will inscribe a downward deflection. Waves that are traveling at a 90 degree angle to a particular lead will create no deflection and is called an isoelectric lead. WebNot all EKGs will have a Q wave. The R wave is the first positive deflection following the P wave. The S wave is the first negative deflection after the R wave.
