If the lack of air is due to the heart, then the person will experience shortness of breath that is not relieved by rest or medications. They may also experience fatigue, chest pain, lightheadedness, dizziness, and difficulty breathing when lying down. They may also experience a rapid or irregular heartbeat, palpitations, and a feeling of tightness or pressure in the chest.
If the person is experiencing any of these symptoms, it is important to seek medical attention immediately. A doctor can perform tests to determine if the lack of air is due to the heart. Tests may include an electrocardiogram (ECG), an echocardiogram (ECHO), a stress test, a cardiac MRI, or a cardiac catheterization.
If the tests show that the lack of air is due to the heart, then the doctor can recommend a treatment plan. This plan may include medications to improve heart function and/or lifestyle changes such as quitting smoking, eating a healthy diet, and exercising regularly. In some cases, surgery may be necessary to correct the underlying issue.
In conclusion, if the lack of air is due to the heart, then the person should seek medical attention as soon as possible. Tests can be done to confirm the diagnosis and then the doctor can recommend a treatment plan.
