Yesterday my mother felt dizziness and increased heart beat rate for 2 minute. After this we consulted doctor they have done ecg and they have told BP level is 150/80 Here are the ecg details below, Vent rate 78bpm Qrs duration 68ms Qt/qtc 364/414 Ms. Pr interval 122ms P duration 102ms RR interval 769ms PRT axes 62 46 34 They have given spasm proxyvon plus as she said some muscle contraction. Insisted to go through 2d echo test. Let me know is that test has to be done early as possible and what is precaution we have to take. Is 150/80 is too risky?
