In the airplane, due to air pressure, gravity changes and other factors, the human physiology will be affected to a certain extent. When the airplane takes off, because the human body presents the phenomenon of overweight, the blood is affected by it to flow to the lower part of the body, causing the heart to eject blood and return blood flow obstacle, which increases the heart load, and in addition to the drop of air pressure, which makes the oxygen partial pressure of blood drop, arrhythmia patients with poor heart function and insufficient compensatory function will have ischemia and hypoxia of the heart and brain, and thus may have accidents. Therefore, from the perspective of aviation medicine, there should be a choice as to whether it is safe for patients with cardiac arrhythmias to fly. According to aviation doctors, any heart rate arrhythmia combined with syncope, ischemic changes in the ST segment of the ECG, Q-wave abnormalities, tachycardia, organic premature arrhythmias, premature arrhythmias in which the R-wave falls very close to the T-wave and other premature arrhythmias in which the cardiac output is severely deficient, type II and III atrioventricular block, severe sinoatrial block, bundle branch block in which organic lesions are combined, and in which the disease has not been Air travel is not an option in cases where the disease is not effectively treated and controlled. Care should also be taken for patients with arrhythmias who choose to travel by air during interictal periods. Airline doctors recommend that patients have adequate sleep and energy before flying, and that they should not fly in an exhausted, suboptimal state. Carrying common and necessary emergency medications is a strong guarantee for a safe flight, and it is important to keep them handy. Before boarding the plane, you should maintain a happy mood and pay attention to exclude the anxious mood when waiting for the plane, especially when the flight is delayed, which is often the main factor triggering cardiac arrhythmia. When waiting for the plane, pay attention to choose a quiet crowd, air flow position, but also pay attention to do not smoke, if there are opportunities and conditions can be appropriate oxygen intake. You can selectively take anti-air sickness drugs or sedative drugs before boarding. During takeoff and landing, pay attention to elevating the lower limbs, leaning back slightly, maintaining steady breathing and relaxing the whole body. Be careful to drink water properly on the plane to maintain body hydration. If you feel unwell, take care not to move, remain calm and take deep breaths, and have the relevant medication ready. If symptoms such as panic, chest tightness and difficulty in breathing occur, take emergency medication immediately, on the other hand, report to the flight crew for assistance in time, and the crew will take emergency measures if necessary.
