Hello friend,
With the question " Shortness of breath, heart palpitations is a sign of what disease? , the doctor would like to answer as follows:
If you have trouble breathing, your heart is pounding, you may have a type of arrhythmia called extrasystoles.
Extrasystoles is a term for an arrhythmia, which is characterized by the occurrence of abnormal premature rhythms that are not under the control of the sinus node (the sinus node is the site of normal rhythm). Early beats may occur singly or multiple beats together and are followed by a break immediately afterwards. The location of these abnormal impulses is used to classify extrasystoles. In clinical practice, extrasystoles include two main types of atrial and ventricular extrasystoles.
Atrial extrasystoles occur when structures in the atria other than the sinus node emit impulses earlier than normal. The heart rate arrives earlier and is compensated by a later pause with a significance equivalent to a longer duration of the heart's contraction. Similarly, ventricular extrasystoles originate from abnormal impulses from the ventricles. This causes the heart to contract earlier but does not guarantee blood flow. Ventricular extrasystoles associated with other cardiovascular conditions is a dangerous context, possibly endangering the life of the patient.
Because arrhythmia is a specialty in the field of Cardiology, you should see a Cardiologist for diagnosis and specific treatment advice.
If you still have questions about heart palpitations, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
