Introduction

Palpitations, chest tightness, and nausea may result from physiological causes, or could be due to pathological conditions such as hypoglycemia or heart failure. When symptoms of heart failure are present, pulmonary circulation becomes congested and the heart's contractile function is impaired, increasing the cardiac workload and leading to symptoms such as rapid heartbeat, chest tightness, and shortness of breath. Additionally, heart failure can cause gastrointestinal congestion, resulting in nausea.

Palpitations, chest tightness, and nausea may be caused by physiological factors, or they could result from pathological conditions such as hypoglycemia or heart failure. Specific details are as follows:

I. Physiological Causes

Excessive emotional stress can trigger the body's stress response, leading to symptoms such as nausea and chest tightness. These symptoms can usually be relieved by deep breathing and timely adjustment of emotions.

II. Pathological Causes

1. Hypoglycemia

When the level of glucose in the blood falls below the normal range, it stimulates the sympathetic nervous system, causing symptoms such as palpitations and nausea. Symptoms typically resolve after sugar intake.

2. Heart Failure

In cases of heart failure, pulmonary circulation becomes congested and cardiac contractile function is impaired, increasing the heart's workload and resulting in symptoms such as rapid heartbeat, chest tightness, and shortness of breath. Additionally, heart failure can cause gastrointestinal congestion, leading to nausea. Treatment typically involves medications such as torasemide tablets or furosemide tablets, taken under a doctor’s guidance.

Furthermore, conditions such as Ménière's disease, acute myocardial ischemia, and acute myocardial infarction can also cause palpitations and chest tightness. It is recommended to seek medical attention at a hospital for proper diagnosis and treatment based on the underlying cause.

Can I get vaccinated if my blood pressure is 155 over 85?

If this blood pressure level has been stably maintained over a long period (e.g., through regular use of antihypertensive medication) and the individual does not experience symptoms such as dizziness, headache, or chest tightness, with overall stable health status, vaccination generally will not cause significant blood pressure fluctuations nor affect vaccine efficacy. After medical evaluation, routine vaccination can be administered, followed by continued blood pressure monitoring.

Is it safe to receive a vaccine with a blood oxygen saturation level of 70%?

Under normal circumstances, individuals with a blood oxygen saturation level of 70% should not receive vaccines. It is important to closely monitor blood oxygen levels daily, ensure good air circulation in the surrounding environment, and avoid enclosed spaces. Rest appropriately according to physical condition and reduce physical exertion. Diet should include foods rich in protein and vitamins to strengthen overall health. Seek medical attention promptly if symptoms such as worsening shortness of breath or chest tightness occur.
