What does a notched QRS complex mean?

A notch in the QRS complex in patients with left ventricular hypertrophy has been suggested to be a result of an intraventricular conduction defect [1]. Injured tissue around an infarct scar resulted in the RSR’ pattern of the QRS complex [2].

What causes QRS fragmentation?

Fragmented QRS complexes (fQRSs), which include various RSR′ patterns, without a typical bundle-branch block are markers of altered ventricular depolarization owing to a prior myocardial scar. We postulated that the presence of an fQRS might improve the ability to detect a prior MI compared with Q waves alone by ECG.

How is LVH calculated?

Left Ventricular Hypertrophy (LVH)

There are numerous voltage criteria for diagnosing LVH, summarised below.
The most commonly used are the Sokolov-Lyon criteria: S wave depth in V1 + tallest R wave height in V5-V6 > 35 mm.
Voltage criteria must be accompanied by non-voltage criteria to be considered diagnostic of LVH.

Where do V1 V2 leads go?

V1 is placed to the right of the sternal border, and V2 is placed at the left of the sternal border.

What is a fragmented QRS?

Fragmented QRS (fQRS) is a convenient marker of myocardial scar evaluated by 12-lead electrocardiogram (ECG) recording. fQRS is defined as additional spikes within the QRS complex.

What is LVH in ECG report?

Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle.

Is LVH serious?

LVH is linked to an increased risk of other problems, including heart attack, heart failure, stroke, and heart rhythm problems. Treatment can help reduce these risks. It can be stressful to learn that you have a problem with your heart.
