ECG Case 001

→

Routine ICU admission ECG in a hemodynamically stable adult.

foundation

ECG Case 002

→

Fever and pain with a regular pulse around 125/min.

foundation

ECG Case 003

→

Sedated ICU patient with a regular pulse around 48/min and preserved blood pressure.

foundation

ECG Case 004

→

The monitor alarms for a very fast rhythm while the patient is awake, speaking, and has a palpable regular pulse.

intermediate

ECG Case 005

→

A shivering patient has a noisy ECG but a stable pulse and normal arterial waveform.

foundation

ECG Case 006

→

Pre-procedure ECG in a stable adult with no cardiopulmonary symptoms.

foundation

ECG Case 007

→

Hypovolemia with a regular narrow-complex rhythm around 115/min.

foundation

ECG Case 008

→

Postoperative patient with a regular narrow-complex rhythm around 52/min.

intermediate

ECG Case 009

→

During transport, the tracing becomes chaotic while pulse oximetry and arterial pressure remain regular.

intermediate

ECG Case 010

→

Rigors produce rapid baseline oscillation across limb leads, but QRS complexes continue at a normal rate.
