If a patient has a tingling sensation in the heart during deep breathing: First, it should be considered that it is caused by traumatic factors, for example, if a patient has a fracture of the sternum or ribs, a stretching injury or contusion of the surrounding tissues, or a sprain of the soft tissues, there will be a significant tingling symptom in the heart during breathing. Second, pneumothorax caused by various factors, such as tension pneumothorax, traffic pneumothorax or open pneumothorax, will also have obvious stabbing pain in the precordial region when breathing deeply. Third, for respiratory infections, in large lung infections, pleural effusion, acute pleurisy, there will also be stabbing pain in the heart with breathing. Fourth, for cardiogenic diseases, such as coronary artery disease unstable angina, acute myocarditis, acute pericarditis, malignant arrhythmia, and severe heart failure, there will also be occasional clinical symptoms of tingling in the heart during deep breathing, but usually accompanied by chest tightness, shortness of breath, and other symptoms.
