Arrhythmia

#arrhythmia, #atrial fibrillation, #bradycardia, #tachycardia, #pacemaker, #ventricular fibrillation, #stroke, #anticoagulants, #dizziness, #spinning sensation, #unsteadiness, #vision going dark, #collapse, #loss of consciousness, #fainting, #lack of energy, #lethargy, #persistent fatigue, #rapid heartbeat, #pounding heart, #fast pulse

An arrhythmia is a condition in which the heartbeat is abnormally slow, fast, or irregular. The heart beats about 100,000 times a day to supply blood to the whole body, and when there is a problem with this rhythm, various symptoms may occur. The types and causes of arrhythmia vary, so if you have symptoms, be sure to consult a medical specialist.

Atlantoaxial Instability (Cervical Instability)

#cervical instability, #first cervical vertebra (C1), #second cervical vertebra (C2), #cervical disc herniation, #cervical spine surgery, #rheumatoid arthritis, #cervical fusion, #spinal cord, #numbness in hands and feet, #arm numbness, #tingling leg, #weakness in arms and legs, #difficulty moving one side of the body, #anxious feeling in the chest, #restlessness, #worrying for no reason

Cervical instability (atlantoaxial instability) is a condition in which the connection between the first and second neck bones (cervical vertebrae) becomes loose and allows excessive movement. Mild cases may cause no symptoms, but as it progresses it can compress the spinal cord and lead to serious nerve damage. It is relatively common in patients with rheumatoid arthritis. Please be sure to decide on an accurate diagnosis and treatment approach through a medical specialist.

Vertebral Compression Fracture

#vertebral fracture, #compression fracture, #spine, #back pain, #osteoporosis, #fall, #fracture in older adults, #bone cement, #dry cough, #persistent cough, #cough that won't stop

A vertebral compression fracture occurs when the impact of a fall onto the buttocks is transmitted to the spine, although in severe osteoporosis a vertebra can also collapse gradually without a significant impact. Severe back pain, including pain with coughing, is a main symptom. In older adults, prolonged bed rest during recovery can lead to complications such as pneumonia or pressure sores, so caution is needed. If you have back pain after a fall, please consult an orthopedic specialist.
