Objective To observe pulsative index (PI), resistant index (RI) of placental helicine arteries by colour Doppler, analyses relation between PI, RI and developing of pregnant hypertension.
Type 1, called Mobitz 1 or sometimes Wenckebach, happens is when the PR interval gets progressively longer with each beat until a P-wave is blocked completely.
If the heart is beating fast enough, the p-wave from the premature atrial contraction might happen at the same time as the t-wave from the previous, normal contraction.
Your body floods that area with blood to try and return it to body temperature and in the process your blood vessels expand, which causes that throbbing pain.
