frs87,
thanks for the post.
1 - I would like to know if PACs, in a
normalNormal saline flush structured heart, can cause PSVT without an abnormal pathway on your heart. We know PACs can trigger
arrhythmiasArrhythmias if there is an abnormality in the electrical system. But even if it doesn’t, is it possible to have, for example, five beats (PACs) in a row configuring a PSVT?
PACs can certainly trigger PSVT. However, the definition of PSVT involves having an abnormal electrical circuit in the heart. If you had 5 or more PACs in a row without a pathway continuing the rhythm, it would be classified more as an ectopic atrial tachycardia or rhythm.
2 - You know anything about the relationship between “pectus excavatum” (congenital deformity of the sternum, which is pressed into the chest, resulting in a 'caved-in' or sunken appearance) and the presence of arrhythmias?
There are loose asscoiations with prolapse and some arrythmias. Most of the issues with pectus relate more to the altered breathing mechanics from the thoarcic wall.
3 – A subtle MVP can cause any pain?
No. There are no nerves in the mitral valve itself.
good luck
