What does cardiomyopathy look like on ECG?

What does cardiomyopathy look like on ECG?

The classic ECG finding in hypertrophic obstructive cardiomyopathy is large dagger-like “septal Q waves” in the lateral — and sometimes inferior — leads due to the abnormally hypertrophied interventricular septum. Criteria for left ventricular hypertrophy is usually present.

Can cardiomyopathy be seen on ECG?

Electrocardiogram (EKG or ECG): An EKG records the heart’s electrical activity, showing how fast the heart is beating and whether its rhythm is steady or irregular. An EKG can be used to detect cardiomyopathy as well as other problems, including heart attacks, arrhythmias (irregular heartbeats) and heart failure.

What is the most common ECG finding with cardiomyopathy?

The ECG is abnormal in over 90 percent of patients with hypertrophic cardiomyopathy. The most common abnormalities are left ventricular hypertrophy, ST-segment alterations, T-wave inversion, large Q waves and the peculiar diminution of R waves in the lateral precordial leads seen in this patient.”

Does ECG show hypertrophic cardiomyopathy?

Test based on electrocardiograms (ECG) that record the heart electrical activity can help in early detection of patients with hypertrophic cardiomyopathy (HCM) where the heart muscle is partially thickened and blood flow is (potentially fatally) obstructed.

Can Blood Work detect cardiomyopathy?

One blood test can measure B-type natriuretic peptide (BNP), a protein produced in your heart. Your blood level of BNP might rise when your heart is in heart failure, a common complication of cardiomyopathy. Genetic testing or screening. Cardiomyopathy can be passed down through families (inherited).

Does alcohol cause cardiomyopathy?

Excessive alcohol intake can lead to high blood pressure, heart failure or stroke. Excessive drinking can also contribute to cardiomyopathy, a disorder that affects the heart muscle.

Can cardiomyopathy be missed?

Unlike blood tests that produce quantitative results, the ECG result is based on physician interpretation that requires prior knowledge and experience. Failure to recognize the cardiac etiology of DCMs that manifest on an ECG can result in a delayed or missed diagnosis with potentially morbid or even fatal outcomes.

Can an EKG detect a heart murmur?

It can reveal if your heart is enlarged, which may mean an underlying condition is causing your heart murmur. Electrocardiogram (ECG). In this noninvasive test, a technician will place probes on your chest that record the electrical impulses that make your heart beat.

Is cardiomyopathy a serious heart condition?

Cardiomyopathy can lead to serious complications, including: Heart failure. Your heart can’t pump enough blood to meet your body’s needs. Untreated, heart failure can be life-threatening.

What are the ECG features of hypertrophic cardiomyopathy (HCM)?

ECG features of Hypertrophic Cardiomyopathy 1 Left ventricular diastolic dysfunction may lead to compensatory left atrial hypertrophy,… 2 There is an association between HCM and Wolff-Parkinson-White… 3 Atrial fibrillation and supraventricular tachycardias are common. Ventricular dysrhythmias (e.g.

What are the most common ECG abnormalities?

The most common ECG abnormalities are those associated with atrial and ventricular hypertrophy — typically, left sided changes are seen but there may be signs of biatrial or biventricular hypertrophy.

What are the signs and symptoms of cardiomyopathy?

Multiple findings such as T-wave inversion, ST-segment depression, and pathologic Q waves are present in patients with cardiomyopathy.

Can a HCM patient have an abnormal ECG without LVH?

There is a small subset of patients with HCM who will have an abnormal ECG with no evidence of LVH on echo. If these patients present with symptoms (e.g. chest pain, exertional syncope) and have a characteristic HCM ECG (showing LVH and dagger-like Q waves), they need to be referred for a cardiac MRI.
