  2. খ
    AF
  3. গ
    SVT
  4. ঘ
    VT
ব্যাখ্যা
During episodes of AF, the atria beat rapidly but in an uncoordinated and ineffective manner. The ventricles are activated irregularly at a rate determined by conduction through the AV node. This produces the characteristic ‘irregularly irregular’ pulse. The ECG shows normal but irregular QRS complexes; there are no P waves.

ব্যাখ্যা
Explanations:
Cells contain a variety of organelles that perform specialized cell functions. The nucleus is an organelle that contains DNA and is the site of gene transcription. The endoplasmic reticulum and the Golgi apparatus are important in protein processing and the targeting of proteins to correct compartments within the cell. Lysosomes and peroxisomes are membranebound organelles that contribute to protein and lipid processing. Mitochondria are organelles that allow for oxidative phosphorylation in eukaryotic cells and also are important in specialized cellular signaling.

A 45-year-old woman presents with episodic dizziness, tinnitus, and hearing loss in her left ear. What is the most likely diagnosis?

  2. খ
    Meniere’s disease
  3. গ
    Vestibular neuritis
  4. ঘ
    Acoustic neuroma
ব্যাখ্যা
Stem Breakdown:

Episodic dizziness, tinnitus, and hearing loss: This triad of symptoms is classic for Meniere’s disease, a disorder of the inner ear.
Left ear involvement: Meniere’s disease often affects one ear initially.
Option Analysis:

A) Benign paroxysmal positional vertigo (BPPV): BPPV causes brief episodes of vertigo triggered by head movements, but it is not associated with hearing loss or tinnitus.
B) Meniere’s disease: This is the correct diagnosis. Davidson and Harrison explain that Meniere’s disease is caused by abnormal fluid accumulation in the inner ear, leading to episodes of vertigo, tinnitus, and fluctuating hearing loss. It is typically unilateral, affecting one ear initially.
C) Vestibular neuritis: Vestibular neuritis causes acute vertigo due to inflammation of the vestibular nerve, but it does not cause hearing loss or tinnitus.
D) Acoustic neuroma: Acoustic neuroma (vestibular schwannoma) can cause unilateral hearing loss and tinnitus, but it typically presents with gradual onset rather than episodic symptoms. Vertigo is less common.
