In the case of hot palpitations, characterized by symptoms like rapid pulse, thirst, and weight loss, treatments often involve cooling the body and strengthening the heart.

Chest pain can be a scary symptom – it's not always serious, but it can be a symptom of having a heart attack. Look out for these signs.
