Left ventricular hypertrophy - Symptoms and causes - Mayo Clinic Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber, called the left ventricle This thickening may increase pressure within the heart The condition can make it harder for the heart to pump blood The most common cause is high blood pressure
Ejection fraction: An important heart test - Mayo Clinic Ejection fraction is a measurement of the percentage of blood leaving the heart each time it squeezes When the heart squeezes, it's called a contraction Ejection fraction is just one of many tests your healthcare professional may use to see how your heart works The heart squeezes and relaxes When the heart squeezes, it pumps out — or ejects — blood from the two lower heart chambers
Heart failure with preserved ejection fraction (HFpEF): More than . . . Mayo Clinic studies test acute inhaled sodium nitrite compared with placebo in people who have heart failure with preserved ejection fraction (HFpEF) and rate adaptive atrial pacing in people with HFpEF and chronotropic incompetence
Implantable cardioverter-defibrillators (ICDs) - Mayo Clinic An implantable cardioverter-defibrillator, also called an ICD, is a small battery-powered device placed in the chest It detects and stops irregular heartbeats, also called arrhythmias An ICD constantly checks the heartbeat It delivers electric shocks, when needed, to restore a regular heartbeat

Atrial fibrillation - Symptoms and causes - Mayo Clinic Atrial fibrillation (AFib) is a heart rhythm disorder In a typical heart, a group of cells called the sinus node sends electrical signals that start each heartbeat The signals go across the upper heart chambers to the AV node, where they usually slow down Then the signals go to the lower heart chambers, causing them to squeeze and pump out blood But in AFib, the signals in the upper
