Generally, during a fever, the heart rate may increase by approximately 12 beats per minute for every 1°C rise in body temperature. Consequently, tachycardia often occurs alongside symptoms such as palpitations and shortness of breath. Prompt and active treatment is essential. For high fever, antipyretic medications can be administered to reduce body temperature. Simultaneously, the underlying cause of the fever must be identified. It is advisable to consult a pulmonologist at a hospital, where routine blood tests, chest radiography, and other diagnostic evaluations can be performed to establish an accurate diagnosis and guide appropriate pharmacotherapy.
