Just saw my lexiscan report, every thing was normal. EF 78% but have 1 st degree AV block. Is this serious? Cardio said no sign of blockages. I am 75
Electrical vs fluid: Imagine a pump with loose wiring from the switch to the motor. Could there be a delay (after turning on the switch) before the pump starts working, but the pump works fine? That's the analogy. 1st degree AV block is an electrical delay on EKG from the switch (upper atria) to the motor (lower ventricular chambers). It says nothing about how the blood moves, which is in the nuclear stress images. ...Read more

Had a stress test done and my target heart rate was 190 but when injected with lexiscan my heart only did 175 is that good or bad?
Max predicted HR...: Exercise stress testing requires that the patient reach 85% of maximum predicted heart rate. Maximum predicted heart rate is given by equation (220-age). If adequate heart rate is not achieved then pharmacologic (lexiscan) stress test can be performed. ...Read moreSee 1 more doctor answer
Nuclear Stress w/ Lexiscan shows moderate to severe ischemia anterior/apical wall. Cath scheduled, doc thinks no blockage, why? I have LBBB; no other defects LV normal size and function, 50% EF. Y?
Need cath: I do not know why the doc feels no blockage. If the stress is abnormal you need to clear up why this is. if you are having these tests, you have had to have had symptoms. 50% Ef is good and the echo being normal does not tell us why. Have the cath. Males are more likely to have abnormal caths and may require some intervention. ...Read moreSee 1 more doctor answer
Had a nuclear stress test done today. Due to dvt, couldn't do treadmill instead they used lexiscan. Read about lexiscn leading to heart att. Worried.
Don't Worry Be Happy: The risks you were worried about relative to the Lexiscan injection would have occurred during the test. Such risks are present for any stress test which is why they are always done with a physician and resuscitation equipment available. Every test we take or don't take is associated with some risk. We try to balance risk vs benefits. ...Read moreSee 1 more doctor answer

What heart tests are done before a decision for a heart cath .Ive had several . EKG, stressecho, Ct score, lexiscan, echo, 21 day monitor. All normal?
There are none...: Even the strongest opiates only "take the edge off" for people in chronic pain. Meds are only one part of dealing with the pain. A useful tool, but pain is so necessary for survival that we are not "allowed" to monkey with it much. In acute pain, the transition from miserable to less miserable can be great. In chronic pain, it's just part of the plan. ...Read more
