ECG Axis Interpretation

ECG Axis Interpretation ECG Axis Interpretation using the schematic illustration demonstrates the relationship between QRS axis and the frontal leads of the ECG. Normal Axis = QRS axis between -30° and +90°.Left Axis Deviation = QRS axis less than -30°.Right Axis Deviation = QRS axis greater than +90°.Extreme Axis Deviation = QRS axis between -90° and 180° (AKA “Northwest Axis”). Methods of ECG Axis Interpretation There are several complementary approaches to estimating QRS axis, which are summarized below: Method 1 of ECG Axis Interpretation– The Quadrant Method The most efficient way to estimate axis is to look at LEAD I … Read more

ECG in Coronary Artery Disease | On-demand

Coronary Artery Disease is the most common acquired disease of modern era. Depending on the severity of ischaemia, coronary artery disease it can present as- ECG is an important, easily available and reliable tool for diagnosing and planning treatment of a patient with CAD. However, clinical judgement other investigations are often required to confirm the diagnosis because ECG may not reflect the actual severity of ischaemia and underlying damage. ECG can be normal in 1-6% of patients with Acute Coronary Syndrome, so, it becomes important to repeat the ECG at regular intervals in such cases. Repeating the ECG may reveal … Read more

Failure to Capture in Pacemakers and ICD

Definition: Failure to capture means when the pacemaker initiates a stimulus, but it fails to depolarise the myocardium. It is depicted on ECG by the presence of spikes of pacemaker but there is no associated depolarisation of the concerned chamber. Causes of failure to capture are: This ECG shows: Cause: Intermittent Failure to Capture. If we carefully see lead V1, we can see progressive widening of QRS. But, at the same time we can see that P waves are preceded by QRS complex every time. What could be the reason? This is rate-dependent widening of QRS also known as use-dependent … Read more
