Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry. I will try to explain you something and give you my opinion. This had to do with a heart rhythm issue. You may have this sensation like your heart is going out of chest for different reasons. It might be a simple sinus tachycardia. This mean that your heart beats over 100 beats for minute. It might be another arrhythmia like atrial fibrillation. It means that your heart rhythm it's not normal but beats in a chaotic way. Or it might be an extra systolic beat, a premature heart contraction. All this rhythm issues makes you feel palpitation, feeling like your heart is racing or going out of chest, difficulty in breathing deeply like the air is not enough. There are different causes of this rhythm issue like simple stress, coffee and alcohol consumption. Also, pathologies like anemia, hyperthyroidism or ischemic heart disease might be other causes. So, if I was your treating doctor I will recommend some examination like an electrocardiogram, a cardiac echo, a full blood analyze, your thyroid hormones, a holder rhythm monitoring and a stress test. Only after this we can judge what we are dealing with and how to treat it. It might be just a stressed period, and it will pass. Hope I was helpful. Wish you good health. Best regards.
