Difference between myocardial ischemia and aortic dissection?
in myocadial ischemia, pain radiate to jaw, neck,shoulder,arm wheras in aortic dissection pain radiate to back, between scapulae there is differense between pulse rate of both arms and leg depending on ecg changes
What can a T-wave inversion can be seen in?
T-wave inversion can be seen in various conditions, including myocardial ischemia, myocardial infarction, electrolyte imbalances, pericarditis, myocarditis, and certain medications affecting the heart's electrical conductivity. It is important to consider clinical context and other ECG findings when interpreting T-wave inversions.
What is ST abnormality?
ST abnormality refers to abnormal changes in the ST segment of an electrocardiogram (ECG). It can indicate myocardial ischemia, injury, or infarction. ST abnormalities are important indicators of heart conditions and often prompt further evaluation and treatment.
An enlarged R wave on an ECG would indicate?
< A myocardial infarction.
What is the most common reason for alarm to sound during ecg?
myocardial infarction
What condition contributes to a reduction in the size of the T wave?
Conditions such as hypokalemia (low potassium levels) or myocardial ischemia can contribute to a reduction in the size of the T wave on an electrocardiogram (ECG). These conditions can affect the repolarization phase of the cardiac action potential, leading to changes in the T wave morphology.

ECG Machine is the process of producing an electrocardiogram( ECG or EKG), a recording of the heart's electrical activity. It's an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle( heartbeat). Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances( such as atrial fibrillation and ventricular tachycardia), inadequate coronary artery blood flow( such as myocardial ischemia and myocardial infarction), and electrolyte disturbances( such as hypokalemia and hyperkalemia).
Differentiate myocardial ischemia from myocardial infarction?
Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as creatine kinase and troponin.
What is the definition of recent myocardial infarction?
recent MI is after the 24hrs from the symptoms onset with Q wave on the ECG
What changes can occur on an ECG due to coronary artery disease?
Changes on an ECG due to coronary artery disease can include ST-segment depression or elevation, T wave inversion, and the presence of pathological Q waves. These changes may indicate myocardial ischemia, injury, or infarction caused by reduced blood flow to the heart muscle from narrowed or blocked coronary arteries.
What does t inversion v3 show on ecg?
T inversion in lead V3 on an ECG may indicate various conditions such as myocardial ischemia, ventricular strain, or electrolyte imbalances. It is important to consider the clinical context and the overall ECG findings when interpreting T-wave inversions in lead V3. Additional testing and evaluation may be necessary to determine the underlying cause.
What is the composite recording of all nodal and myocardial action potentials?
The composite recording of all nodal and myocardial action potentials is known as an electrocardiogram (ECG). It provides valuable information about the electrical activity of the heart, including the spread of impulses through the atria and ventricles, heart rate, and rhythm. By analyzing the ECG waveform, healthcare professionals can assess the heart's function and diagnose various cardiac conditions.
