Abstract:
An 80-year-old man with acute type A aortic dissection, who was preoperatively observed in the intensive care unit, suddenly became unresponsive. The patient was immediately intubated, but a pulse check was delayed because the cardiac monitor seemingly showed a normal sinus rhythm. Bedside echocardiography, while continuing cardiopulmonary resuscitation, revealed massive pericardial effusion. It indicated the patient's cardiac arrest was pulseless electrical activity (PEA) due to cardiac tamponade. After pericardiocentesis, a perfusion rhythm was restored with palpable distal pulse. He successfully underwent a prosthetic graft replacement of the ascending aorta and was discharged after physical rehabilitation.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
