Chest pain can sometimes be a sign that there could be a problem with your heart. This happens because your heart might also be starved for oxygen because it could either be beating too fast, or is beating at an inconsistent rhythm.
In some cases, strong emotions, such as anxiety, fear, or stress can also force your heart to deviate from the normal pulse and heart rate and cause chest pain. Regardless, it would be a good idea to talk to your doctor about it to rule out any possible problems.
Dizziness can occur in people with either tachycardia or arrhythmia. Similar to shortness of breath, dizziness can occur because the heart is not pumping enough blood throughout the body.
And just like the rest of your organs, the brain needs fresh oxygenated blood in order to function properly. If there’s not enough fresh blood going to the brain, then a person can experience dizziness and lightheadedness.
