What is the difference between echocardiogram and electrocardiogram?
Welcome to Health Care Magic
Both the ECGs are within NORMAL limits
There is no significant change between the two
In the ECG, there are beat to beat changes… it is the not the change over time, but absolute values that need attention
The rSr’ pattern (also called incomplete Right Bundle Branch pattern) seen in V1 lead is a normal variant… [Rarely due to conduction system or right sided heart issues]
An ECHOcardiogram is routinely done to see the heart valves / heart muscle and heart function (Ejection fraction, wall motion abnormality) / clots... / and so on
TMT (Treadmill exercise ECG) is also done routinely to evaluate ischemia (reduced blood flow / Coronary Artery Disease)
This ECG does not warrant any concern. Only if there are symptoms like palpitation, blurred vision, dizziness, loss of consciousness, shortness of breath, along with this, further assessment is done.
God bless you
Need further assessment & assistance
That is an indication for further assessment and assistance…
Standard ECG records the electrical activity of the heart, for a few seconds. It can detect the arrhythmia occurring during that time only. If the episode occurs randomly or is precipitated by a specific activity like exercise - one needs Holter or event monitor. Holter records for days; Event Monitor for weeks… Holter records continuously; Event Monitor only at certain times. This super-speciality cardiology expert is called Electro-Physiologist.
As the stress test (Treadmill Exercise ECG), the next step is TMT with thallium isotope (Stress imaging). It is the ideal non-invasive way to evaluate ischemia / to assess the function (PHYSIOLOGY) – to see whether the blood arriving at the heart muscle.
The next step is to see the ANATOMY (structure) – undergo catheterisation and coronary angiography with a view for possible intervention. It is the only way to directly ‘see’ the block, if any – and its location, extent, severity and so on. Coronary arteriography is invasive but it is the gold standard for this. / CT angio is non-invasive study for the anatomy. If positive, she will need catheterisation, anyway.
The treating doctor alone could conclude better based on total clinical picture…
