Respirophasic Variations in the QRS Complex and Echocardiographic Equivalent in Pulmonary Embolism

A respirophasic variation of the QRS complex was observed in a patient with bilateral pulmonary embolism and pulmonary hypertension. An analogous variation of the Sa systolic velocity of the tricuspid annular tissue Doppler imaging was also noticed. Both phaenomena persisted until the clinical and h...

Sumario:A respirophasic variation of the QRS complex was observed in a patient with bilateral pulmonary embolism and pulmonary hypertension. An analogous variation of the Sa systolic velocity of the tricuspid annular tissue Doppler imaging was also noticed. Both phaenomena persisted until the clinical and haemodynamic improvement of the patient. A mechanistic approach of the electric phaenomenon is proposed.
