Is it really cardiac problem or not ?

Based on the symptoms you’re describing—low blood pressure, high pulse, chest pain, arm and shoulder pain, fatigue, nausea, vomiting, and pain with inhalation and exhalation—there could be several potential causes, but these could definitely signal a cardiac issue or something else that requires immediate medical attention. The combination of chest pain, shoulder pain, and nausea especially makes it essential to consider conditions like a heart attack or angina. It’s critical to take these symptoms seriously as they could be indicative of a heart event, pericarditis, or even a pulmonary embolism. You should seek medical attention immediately—go to the emergency room or call emergency services. Time is valuable in these situations, and a healthcare provider needs to conduct a thorough examination. They may run tests like an ECG, blood tests, or imaging studies to determine the cause of your symptoms. It might seem like anxiety could also cause symptoms like these, but it’s less likely given the whole picture here, so it’s not something to dismiss as non-urgent. If it turns out not to be cardiac-related, other things they might consider are muscle or bone issues or even gastrointestinal problems like reflux which can mimic cardiac symptoms but again, those aren’t things to attempt to diagnose without proper equipment and expertise. Until you are able to get medical assistance, try to stay calm, avoid any exertion, and if possible, have someone with you to help. Remember, this isn’t a situation to take lightly, and procrastination here could be dangerous. Prenatal precautions and emergency interventions can significantly improve outcomes if this is something like a heart attack.
