Palpitations in a 64-year-old man.
Heart (British Cardiac Society)
|November 28, 2013
Summary
A 64-year-old man experienced irregular palpitations. Cardiac MRI revealed asymmetrical septal hypertrophy and interventricular septum hyperenhancement, suggesting hypertrophic cardiomyopathy.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Cardiac Electrophysiology
Background:
- Understanding the diagnostic markers for cardiac conditions is crucial.
- Intermittent palpitations can indicate underlying cardiac abnormalities.
- Electrocardiography (ECG) and Cardiac Magnetic Resonance (CMR) are key diagnostic tools.
Observation:
- A 64-year-old male presented with intermittent irregular palpitations.
- No prior history of cardiac disease, hypertension, or syncope was reported.
- A 12-lead ECG showed sinus rhythm with premature atrial and ventricular contractions.
Findings:
- ECG revealed high QRS voltages, consistent with left ventricular hypertrophy (LVH).
- Cardiac MRI demonstrated asymmetrical septal hypertrophy.
- Significant mid-myocardial hyperenhancement of the interventricular septum was observed on CMR.
Implications:
- These findings suggest hypertrophic cardiomyopathy (HCM).
- CMR is vital for characterizing myocardial structure and enhancement patterns in HCM.
- Early diagnosis and management of HCM can prevent adverse cardiac events.

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

735
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

01:14Decreased pulse rate
1.0K
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

2.5K
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
