Top 10 Online ECG Courses

Following is a list of top 10 online ECG courses I have researched the internet as well as used my own experience to make a list of top 10 online ECG learning courses. Why is it important to learn ECG courses? An electrocardiogram (ECG or EKG) is a quick test to check the heartbeat. It records the electrical signals in the heart. Test results can help diagnose heart attacks and irregular heartbeats, called arrhythmias. ECG machines can be found in medical offices, hospitals, operating rooms and ambulances. Some personal devices, such as smartwatches, can do simple ECGs. Ask your healthcare … Read more

Left Bundle Branch Block (LBBB)

LBBB ECG :- Left Bundle Branch Block or LBBB is the result of a delay or interruption of conduction within the left bundle branch. In complete LBBB, the duration of QRS is >120ms and in incomplete LBBB it is between 100 and 120 ms.   Complete LBBB ECG features :- Significance of complete LBBB- Incomplete Left Bundle branch Block- In the case of incomplete LBBB, conduction through the left bundle branch and its ramifications is still possible but will be delayed. This is in cintrast to complete LBBB where conduction through the left sided specialised conduction system is no longer … Read more

Wolff-Parkinson-White Syndrome (WPW) – The Great Mimicker

The Wolff-Parkinson-White syndrome is an electrocardiographic syndrome which is the expression of an anomalous atrioventricular conduction pathway, congenital in origin. This pathway forms a bypass which enables the supraventricular impulse to bypass the AV node, bundle of His and distal conducting system, and so activate or pre-excite the ventricles. The anomalous bypass is also known as the Bundle of Kent, is a thin filamentous structure which may be situated ectopically anywhere along the atrioventricular ring – the fibrous junction separating the atria from the ventricles. Basic ECG presentation of WPW Syndrome Other pathologies mimicked by WPW syndrome

Hypertrophic Cardiomyopathy (HCM)

Hypertrophic Cardiomyopathy is a hereditary disorder that is typically inherited in an autosomal dominant fashion with variable penetrance and expressivity. The hallmark of the disorder is myocardial hypertrophy that is inappropriate, often asymmetrical, and occurs in the absence of an obvious inciting hypertrophy stimulus. This hypertrophy can occur in any region of the left or right ventricle, but frequently involves the interventricular septum, which in nearly quarter of patients results in an obstruction of flow through the left ventricular outflow tract. Mutations involving genes coding for sarcomeric proteins accounts for most cases of HCM. ECG manifestations of HCM: Ventricular Hypertrophy … Read more

Electrical Alternans

Electrical Alternans is an electrocardiographic manifestation in which there is alternation in the amplitude of the QRS complex, the T wave alone, OR Both QRS and T wave. It often accompanies fast rates and then has no prognostic significance. When found with slow rates, it connotes organic heart disease with an adverse prognosis. Electrical Alternans may occasionally be associated with a pericardial effusion and is usually seen in midprecordial leads. Electrical Alternans does not cause a disturbance of rhythm.
