👉 The term "tachyphylactic" refers to a condition where the heart is pumping blood too fast, causing symptoms such as chest pain or discomfort. This can be caused by various factors such as high blood pressure, heart disease, or other medical conditions that affect the heart's ability to pump blood efficiently. Tachyphylaxis can lead to serious complications, so it's important to seek medical attention if you experience any symptoms of tachycardia (fast heartbeat).
