What does IVCD stand for?
What does IVCD stand for?
Families and physicians often wonder what the terms“intraventricular conduction delay” (IVCD) or “incomplete right bundle branch block” (IRBBB) or “rsR’” on an electrocardiogram mean and what to do with the information.
Which is correct exercise stress test or exercise ECG?
Indeed, clinicians often use the term exercise ECG instead of the correct term exercise stress test. However, the ECG is only one of the parameters that must be evaluated and the final result of the test depends on an integrated assessment of six components: ECG reaction: ST changes, T-wave changes, arrhythmias, conduction defects
How to communicate concerns about nonspecific changes on ECG?
Communicating concerns about nonspecific changes on ECG Although very common, nonspecific ST-T (NSST-T) wave changes on ECG are often misunderstood, poorly explained to patients, or prematurely dismissed by clinicians. On initial hospital presentation, only about 50% of patients presenting with chest pain have an ECG diagnostic of acute MI.
What does ST segment depression mean on the ECG?
In summary: ST segment depression is the hallmark of myocardial ischemia (during exercise) on the ECG. ST segment depression may be isolated or accompanied by T-wave inversions (negative T-waves). T-wave inversion (negative T-waves) never appear without simultaneous ST depression in patients with myocardial ischemia.
What are the implications of NSST-T wave changes on ECG?
Even though NSST-T wave changes may represent a benign ECG finding, other conditions that may cause or be associated with these abnormalities should be considered. Do not assume that all is well because “classic” changes of acute ischemia or MI are absent. Many clinicians fail to seriously consider the implications of NSST-T wave changes on ECG.
What are the results of an ECG stress test?
ECG stress tests find severe blockages of 70% or more. Heart attacks can occur with smaller blockages that break off and form clots. These smaller blockages often don’t cause symptoms, like the larger ones do, until a heart attack happens.
Can a negative ECG test cause a heart attack?
A negative ECG stress test doesn’t guarantee you won’t have a heart attack or other problem. ECG stress tests find severe blockages of 70% or more. Heart attacks can occur with smaller blockages that break off and form clots. These smaller blockages often don’t cause symptoms, like the larger ones do, until a heart attack happens.

What does the ST-segment depression on an ECG mean?
ECG performed at her highest heart rate ( Fig. 1) shows sinus tachycardia at a rate of 112 bpm, with a 1-mm horizontal ST-segment depression at 80 ms after the J-point, in the inferolateral leads (II, III, aVF and V4–6), which is suggestive of ischaemia due to obstructive coronary artery disease (CAD).
