Well explained! Besides, the ERPS among young male can be intermittent.. not a consistent finding .. i kinda think the ERPS among young male may be caused by “electrolytes deficiency” secondary to their high level of physical activities.
A good suggestion on the cause. But we find actual electrolyte deficiencies like hyponatremia very often in the elderly rather than in the young. May be there could be difference in potassium or magnesium levels in the active young, which are within the 'normal range', but could still cause changes in the ECG? My mentor used to mention that potassium supplementation could cause disappearance ERPS pattern.
You have seen the left right shunt flow as red in colour. Right to left shunt in the same location will be blue in colour, meaning flow from right atrium to left atrium.
First locate the pulmonary valve on parasternal short axis view by 2-D echo. Then place the cursor exactly over the pulmonary valve leaflet and select M-Mode.
Digoxin effect is seen in leads oriented to the dominant ventricle. Usually lateral leads as left ventricle is dominant. In case of right ventricular hypertrophy, it is seen in anterior leads. But in case of digoxin toxicity, it can be seen in both sets of leads. That is the mirror image correction mark type of ST-T changes. As you are aware, ventricular ectopy and AV block will manifest in all leads.
