Q. Electrocardiography: Why is the ECG termed as "PQRST" and not (for example) ABCDE?
Doctor Answer is medically reviewed by SecondMedic medical review team.
ECG stands for electrocardiography, an important medical diagnostic tool used to detect irregularities in the electrical activity of the heart.
The components that make up an electrocardiogram are referred to by their initial letters: P, Q, R, S and T. Each component stands for a corresponding stage of cardiac electrical cycle known as 'the cardiac rhythm'. The P-wave corresponds with atrial depolarization; the Q-wave represents depolarization leading to ventricular contraction; the R-wave suggests ventricular systolic excitation; and finally, the S-T segment invites repolarization.
Therefore ECG is termed as ‘PQRST’ and not (for example) ABCDE as these five letters represent distinct stages of cardiac electrical cycle in sequence. This sequence is integral diagnostically in order to accurately examine a patient's heart rhythm or any pathological abnormalities related it.

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
