Final answer:
Not all chest pain is cardiac in nature, and an immediate ECG is not always necessary for every chest pain episode.
Step-by-step explanation:
It is not accurate to say that all chest pain is considered cardiac until proven otherwise. While chest pain can often be a symptom of a cardiac issue, it is not the only possible cause. Other non-cardiac causes of chest pain include anxiety, indigestion, muscle strain, and respiratory issues. It is important to seek appropriate medical attention to determine the cause of chest pain and receive the appropriate treatment.
An ECG (electrocardiogram) is a useful diagnostic tool to assess cardiac activity. However, it does not detect all cardiac problems, and it is not always necessary to get an ECG immediately for every instance of chest pain. The decision to get an ECG should be made by a healthcare professional based on the individual's symptoms, medical history, and risk factors for heart disease.
