Give progesterone > bleeds | It was the one lacking on board (anovulation/PCOS)
Give progesterone > doesnt bleed | try adding estrogen & simulate a menstrual cycle >> If then Bleeds🩸> something’s wrong with the FSH/LH fine tuning
If Estrogen + Progesterone does’nt lead to bleed🩸— check for uterine pathway blockage/structural defects (Asherman’s syndrome) esp. pt having h/o multiple D&C
During ventricular tachycardia, sometimes the SA nodal firing takes control of independent ventricular depolarization for brief moment, as this happens, “CAPTURE BEATS” appear. They are nothing but a brief moment of normal looking P-QRS pattern
Whats a “fusion beat” ?
During ventricular tachycardia, sometimes the SA nodal impulse and the independent ventricular impulse combine together to create a mix looking P-QRS pattern called fusion beats.
