Okay, now remember that GI upset of any nature has to potential to cause palpitations to occur. Although it's a very natural and understandable response, it's important to refrain from cause-and-effect thinking such as what I've described on the forum on several occasions. In other words, realize that the Vagus nerve (which innervates the GI tract as the gastric nerve) will respond to general GI distress and not necessarily or specifically "nausea" or other symptom. So when giving consideration to the underlying cause for increased palpitations, always remember that the vagus nerve is not able to distinguish one type of distress from another, but rather responds and becomes stimulated by GI distress in general.

Stomach viruses typically range from 5 to 7 days before you'll begin to feel fully recovered. Eat soup or small portions of bland food products and get plenty of rest. You'll be fine.

Best regards and Good Health
