Aah, I understand lah, heartbeat yang laju memang bikin risau! Ada banyak reasons sebenarnya, stress, caffeine, kurang tidur, or even anxiety about the heartbeat itself boleh jadi culprit. Satu dua kali ni okay, tapi kalau sering atau diiringi dengan shortness of breath, chest pain, or dizziness, better check with your doctor untuk peace of mind. A few of my mum friends pun pernah experience ni, and once they did proper check-up, they felt so much better knowing everything is fine.
