Physical Examination

Physical findings depend in part on the P-to-QRS relationship with/without signs of AV dissociation.

Vitals

Blood Pressure

Neck

  • Intermittent cannon A waves can be observed on examination of the jugular pulsation in the neck, and they reflect simultaneous atrial and ventricular contraction.

Heart

  • Variability in the occurrence and intensity of heart sounds (especially S1) may also be observed and is heard more frequently when the rate of the tachycardia is slower.
  • Look for evidence of preexisting conditions like a pacemaker/AICD or scar mark from previous cardiothoracic surgery.
