The test can also detect heart abnormalities such as arrhythmias, and conditions affecting electrical conduction within the heart such as various types of fascicular blocks. [3] A "normal" stress test does not offer any substantial reassurance that a future unstable coronary plaque will not rupture and block an artery, inducing a heart attack ...
The most common tests used are an electrocardiogram, an exercise stress test, and a coronary angiography. [29] A variety of laboratory tests may be ordered. An important laboratory test to determine if myocardial damage has occurred is a cardiac troponin value. [20]
Achieving a high enough heart rate at the end of exercise is critical to improving the sensitivity of the test to detect high grade heart artery stenosis. High frequency analysis of the QRS complex may be useful for detection of coronary artery disease during an exercise stress test. [1]
A new heart disease diagnosis approach has led to a 99.1% accuracy in diagnosing heart disease. [18] This new diagnosis approach uses CT-scan imagery to focus on coronary artery diseases and blockages in contrast to angiography. [18] Further research directions in preventing and treating coronary artery disease include: [19]
A nuclear stress test is a diagnostic test that healthcare professionals use to monitor blood flow to your heart before and after exercise. Doctors often order it to look for coronary artery ...
First-degree heart block does not require any particular investigations except for electrolyte and drug screens, especially if an overdose is suspected. [5] In comparison to second-degree atrioventricular block, in first-degree block there is an absence of non-conduction or "dropped beats."
