I'm really worried about my dad. His ECG came back showing sinus mode tachycardia and something called middling left axis deviation. What exactly do these mean? Is it something we should be seriously concerned about? Hes also been experiencing some pain on the left side of his chest. Could these symptoms be related?

Ecg shows Sinus mode tachycardia and Middling left axis deviation. Sinus mode tachycardia refers to a faster than normal heart rate originating from the sinus node in the heart. Middling left axis deviation indicates a slight deviation in the electrical activity of the heart towards the left side. These findings can be seen in conditions like anxiety, dehydration, fever, or heart conditions. It is important to correlate these findings with your symptoms and clinical examination. For your father's chest pain on the left side, it is crucial to rule out any cardiac issues. He should seek immediate medical attention for a proper evaluation, which may include further tests like an ECG, blood tests, and possibly imaging studies. The treatment will depend on the underlying cause of the chest pain.

I'm 32 and recently had a couple of ECG tests that showed an abnormal ECG reading. The first one mentioned sinus bradycardia and a borderline first-degree AV block IV conduction defect. Then, the next day, my ECG showed abnormal results again, this time with right axis deviation. I'm really concerned about whether this is a normal variation or if the machine could have made an error? Is this something dangerous that I should be worried about? What should I do next? Would love your guidance!

Sinus bradycardia with borderline first degree A-V block and right axis deviation on ECG can indicate certain heart conditions. It is unlikely to be a machine error, but it is important to follow up with a healthcare provider for further evaluation and management. In this case, you may need to consult a cardiologist for a detailed assessment and appropriate treatment. The doctor may prescribe medications such as Metoprolol to help regulate your heart rate and rhythm. It is important to follow up with your healthcare provider for proper management and monitoring of your heart health.
