Intra-Aortic Balloon Pump Overview
Intra-Aortic Balloon Pump (IABP) or intra-aortic counterpulsation device the balloon is inflated during diastole to increase coronary perfusion and then deflated during systole to decrease afterload

Catecholamine excess, Beta Blockade and Critical Illness
Catecholamine excess, or 'sympathetic overload', may be harmful in critically ill patients, including those with septic shock. Catacholamine excess is associated with specific conditions such as Takotsubo cardiomyopathy
Tenecteplase (TNK-tPA)
Tenecteplase is a tissue plasminogen activator used as a thrombolytic medication in: Acute Ischaemic Strokes, Acute Myocardial Infarction, PE
Pacing Modes
Pacing Modes – Advantages and Disadvantages
Electromagnetic Interference
electromagnetic interference can affect the function of implanted electronic devices such as pacemakers and ICDs
Temporary Pacemaker Troubleshooting
Temporary Pacemaker Troubleshooting. Problems with pacing: output failure, failure to capture. Problems with sensing: oversensing, undersensing and Pacemaker syndromes
Pacemakers
Pacemakers are devices that detect the electrical activity of the heart and stimulate it to contract at a faster rate.
Overdrive Pacing
Overdrive pacing = pacing the heart at a higher rate than the native heart rate; VT or VF can result -> always have DC cardioversion available
Pulmonary Hypertension
Pulmonary hypertension (PHT) is present when mean pulmonary artery pressure exceeds 25 mm Hg at rest or 30 mm Hg with exercise. Primary PHT is a relatively rare idiopathic condition; Secondary PHT is usually due to cardiac or respiratory cause
STEMI Management
STEMI is a type of acute coronary syndrome that requires emergency reperfusion therapy. Definition and assessment of STEMI is described in Acute Coronary Syndromes
Narrow Complex Tachycardia
Narrow Complex Tachycardia: two main categories: 1. AV node independent; 2. AV node dependent
Myocarditis
Myocarditis: inflammation of heart muscle -> lymphocytic and fibroblast infiltration + myocyte necrosis
