Skin vascular constriction in a reticular pattern is thought to be characteristic of a lightning injury. Electrical shock injury is an injury caused by the passage of electric current through the body. They are usually caused by inadvertent electrocution or lightning strikes. When a person is struck by lightning, heartbeat and respiration often stop immediately, accompanied by myocardial damage, followed by myoglobulinuria and a reticular pattern of vasoconstriction of the skin, which is thought to be characteristic of a lightning injury. This is followed by myoglobulinuria. What are the tests for cutaneous vasoconstriction in a reticular pattern? Electrocardiogram: The heart is excited by the pacing point, atria, and ventricles in succession during each cardiac cycle, accompanied by bioelectric changes, and a graph of multiple forms of potential changes (referred to as ECG) is elicited from the body surface by an electrocardiographic tracer. Ambulatory blood pressure monitoring (ABPM): Ambulatory blood pressure monitoring (ABPM) is an adjunctive test used to check whether blood pressure is normal. Ambulatory blood pressure monitoring is a portable blood pressure monitoring method that uses indirect noninvasive measurements for 24 consecutive hours and tracks and records blood pressure at set intervals. Respiratory motion test: Respiratory motion test is to check the health movement of breathing in a rhythmic motion. Inhalation is immediately followed by exhalation, and after a short interval, the next breath is performed. Generally short inhalation and slightly longer exhalation can change due to excitement, fear and strenuous exercise, etc. Blood pressure: Blood pressure in the prone, sitting and standing positions is an auxiliary test used to check whether blood pressure is normal. Most doctors measure the patient’s blood pressure in the sitting position or in the prone position when they visit the doctor, and if only the prone blood pressure is measured, there is a possibility that the measured blood pressure is high, resulting in long-term misdiagnosis of hypotension. After electrocution, the lighter ones only have painful muscle contractions, panic, pallor, headache, dizziness, and palpitations. Serious cases can lead to loss of consciousness, shock, cardiac and respiratory arrest, and often severe ventricular arrhythmias, pulmonary edema, gastrointestinal bleeding, coagulopathy, and acute renal insufficiency after electric shock. Special clinical attention should be paid to the possibility that the injured person has multiple injuries, including mandatory muscle damage, visceral organ damage, and internal and external burns. Survivors may have cardiac and neurological sequelae.
