Heard and am paranoid about pulsus alternans, would auscultation with stethoscope by doc be enough to rule it out?

Pulsus alternans: "Pulsus alternans" describes alternating stronger/weaker arterial pulse waves. Generally a sign of very poor heart function, & would not be the only sign; a patient with pulsus alternans would also be sick, with fatigue, shortness of breath, & other signs of heart failure. On the other hand, there are other conditions which might mimic pulsus alternans (eg atrial or ventricular bigeminy).
