I'm sorry to hear that you're experiencing a vibrating sensation in your body along with quick anxiety. These symptoms can be distressing. While a feeling of vibration or palpitations can sometimes be related to heart rhythm issues, they are not specific enough on their own to indicate heart disease. Anxiety itself can also cause sensations like trembling or vibrations.

Given that you are concerned about heart disease, it is important to consider other symptoms such as chest pain, shortness of breath, dizziness, or fainting. If you have risk factors like high cholesterol, high blood pressure, or a family history of heart disease, these should be evaluated by a cardiologist (heart specialist).

Since you mentioned anxiety, it might also be helpful to discuss this with a doctor who can assess both your physical and mental health. They may recommend tests such as an ECG (electrocardiogram) or blood tests to check your heart function and rule out any underlying conditions.

Recommendations:

• Keep track of when the vibrations occur, their duration, and any other symptoms.
• Avoid stimulants like caffeine or excessive alcohol, which can worsen palpitations or anxiety.
• Schedule an appointment with a cardiologist to evaluate your heart health.
• Consider consulting a mental health professional if anxiety is significantly affecting you.

If you experience severe chest pain, fainting, or difficulty breathing, seek emergency medical care immediately.
