Frequent dizziness, shortness of breath, heart palpitations is heart disease?

Question
Hello doctor, I have been suffering from palpitations, shortness of breath, dizziness, insomnia for nearly 1 year.. went to many doctors and was diagnosed with no physical heart disease, because when the body is exerted, the rhythm of the body will change. The appearance of tachycardia is clearly a heart disease, but when going to the doctor and doing tests, there is no obvious disease. Ask your doctor for advice.

Hello, the symptoms of palpitations and shortness of breath can be caused by your fast heart rate, but because the symptoms appear from time to time, it is difficult to detect, but still there are symptoms. The way to detect if your heart rate is really fast is by wearing a device called the Holter 24h, which records your heart rate for 24 hours as well as detects your irregular heartbeat.
