Electrocardiogram (ECG/EKG) — ECG/EKG Terminology

Definition: A recording of the electrical activity of the heart using electrodes placed on the skin. It shows the timing and strength of electrical signals as they travel through the heart.

Key Facts

• Surface recording of summed cardiac electrical activity over time.
• Waveform timing and morphology reflect impulse origin and conduction pathway.
• Clinical interpretation requires rhythm context and patient status correlation.

ECG Connection: Telemetry is a continuous limited-lead ECG view used for rhythm surveillance and trend detection.

Why It Matters: Accurate ECG interpretation supports rapid recognition of rhythm deterioration.
