In most infarctions, the EKG will reveal the correct diagnosis. An EKG should be performed immediately on anyone in whom an infarction is even remotely suspected. However, the initial EKG may not always be diagnostic, and the evolution of electrocardiographic changes varies from person to person; therefore, it is necessary to obtain serial cardiograms once […]

Acute Potassium Disorders

15-Jul-17

Disorders of potassium homeostasis are common in hospitalized patients and may be associated with severe adverse clinical outcomes, including death. Prevention and proper treatment of hyper- and hypokalemia depend on an understanding of the underlying physiology. The total body potassium content of a 70-kg adult is about 3500 mmol (136.5 g), of which only 2% […]

[Clinical Art][Circulation] Interpretation of Hemodynamic Waveforms

20-Oct-16

Basic Knowledge Mechanism of Hemodynamic Monitoring The rapidly occurring events (represent mechanical forces) of cardiac chambers and vessels during cardaic cycle require conversion to an electrical signal to be transmitted and subsequently translated into an interpretable, graphic format. The pressure transducer is the essential component that translates the mechanical forces to electrical signals. The transducer may […]
