Death by potassium chloride injection
Potassium chloride is a commonly used electrolyte balance regulator in clinic. Potassium ion is a very important ion. There is more potassium in human cells and more sodium in extracellular fluid. The electrical activity of cells is based on the entry and exit of these two ions. If there is too much potassium, hyperkalemia will occur. It is characterized by weakness, fatigue, numbness of hands, feet and lips, unexplained anxiety, confusion, dyspnea, slow heart rate, arrhythmia, conduction block and even cardiac arrest. Electrocardiogram is characterized by high and sharp T wave (we also call it tent T, which is a very dangerous clinical manifestation), and the P-R interval is gradually prolonged. P wave disappears, QRS wave widens and sine wave appears.

Nitroglycerin is a vasodilator, usually taken orally. Because there is a rich vascular network under the tongue, drugs can easily enter the blood and have an effect soon. This has won valuable time for saving patients with angina pectoris and relieving symptoms.

If a healthy person uses it, it will show the side effects of the drug (in fact, patients also have side effects, just because the drug has a good effect on patients, covering up or weakening the discomfort caused by the side effects), such as headache and postural hypotension.

The combination of these two drugs will cause dysfunction of brain, heart and important organs, such as coma, arrhythmia and inability to pump blood. It is difficult to recover from brain hypoxia for 5 minutes.
