I am tired and just want to ask one question! hehe
On a cellular level... why does Hypercalcemia cause widened QRS and shortened QT interval?
I was writing an email to my nurse educator and honestly i am so tired i just am confused!
"Hypercalcemia and widened QRS and shortened QT"
Widened QRS - Increased Ventricular Depolarization (Increased Contraction)
Shortened QT - Decreased Ventricular Repolarization (Unable to fill ventricular volume)
WIth these both do they explain the reason why he was Tachycardic and Hypertensive on admission because of increased Myocardial Contractility?
Looking @ the Ventricular Myocyte Cardiac Curve and the phases... i see that the Calcium influx is mainly in Phase 2 (Plateau)... this is where i get tired and don't wnat to move on and come to you guys!
If you can help let me know. Otherwise I will retry this again tomorrow. Thanks!
