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.

Cardiac Arrest

#cardiac arrest, #cardiopulmonary resuscitation, #golden time, #targeted temperature management, #automated external defibrillator

Cardiac arrest is a life-threatening emergency in which the heart stops and cannot pump blood to the body. Calling 119, prompt cardiopulmonary resuscitation (CPR) by bystanders, and treatment by an emergency medicine specialist are key to saving the patient's life.

Costochondritis

Costochondritis is a condition in which the cartilage that connects the ribs to the breastbone (sternum) becomes inflamed. Chest pain is the main symptom, and because the symptoms can resemble those of pneumothorax or heart disease, an accurate diagnosis is important. If chest pain persists, please consult a medical specialist.

A herniated cervical disc (cervical disc herniation) is a condition in which a disc between the vertebrae of the neck presses on a nerve. The main symptoms are arm numbness or arm weakness. Most cases can be treated without surgery, but if there is paralysis or loss of bladder or bowel control, please consult a medical specialist immediately.

Herniated Lumbar Disc (Lumbar Disc Herniation)

#herniated lumbar disc, #disc herniation, #intervertebral disc, #radiating leg pain, #sciatica, #low back pain, #spine, #low back ache, #back pain, #lower back strain, #numbness in hands and feet, #arm numbness, #tingling leg, #weakness in the arms or legs, #difficulty moving one side of the body

A herniated lumbar disc (lumbar disc herniation) occurs when a disc between the vertebrae of the spine moves out of its normal position and presses on a nerve. It is characterized by low back pain along with numbness or pain radiating down the leg. With timely treatment, most cases may improve without surgery.

Hypotension (Low Blood Pressure)

Hypotension refers to blood pressure that is lower than normal. Some people have chronically low blood pressure, but when blood pressure that was normal or high suddenly drops, it can lead to serious consequences within a short time. If you experience a sudden drop in blood pressure, please seek prompt evaluation by a medical specialist.

Meniscus Tear

A meniscus tear is a tear in the crescent-shaped cartilage (the meniscus) located between the thighbone (femur) and the shinbone (tibia) in the knee. When this happens, the meniscus may absorb shock less effectively, which can affect the health of the knee joint. If you have symptoms, please consult a medical specialist.

Post-Cardiac Arrest Integrated Care

#cardiac arrest, #cardiopulmonary resuscitation, #defibrillation, #chain of survival, #targeted temperature management, #heart, #emergency

Cardiac arrest is a condition in which the heart stops, cutting off the blood supply to the brain and the rest of the body. Without emergency care within 3 to 5 minutes, serious brain damage can occur, so immediate treatment such as CPR and defibrillation is important, and integrated care by a specialized medical team is needed afterward. If cardiac arrest is suspected, call 119 immediately and receive treatment from a medical specialist.
