Case Report
Provides a visual tracing of pulsus alternans that offers insights into the initiation mechanism of this indicator of severe left ventricular dysfunction.
Aslanger et al. (2024) conducted a case report in Pulsus alternans. A tracing of pulsus alternans was presented, depicting a classic example of alternating strong and weak arterial pulse waveforms and providing clues about its initiation mechanism.
